As the
directors of the
District of Columbia
’s
major cancer research and treatment centers, we see the consequences of cancer
in our community every day.
As much as
the cancer centers and cancer-related organizations in the District work to
reduce the number of people being diagnosed with, suffering from, and dying
from cancer, we realize that much more is needed. The Cancer Plan before you
provides a blueprint for the next steps to be taken if we are to make
meaningful progress toward reducing suffering and death from cancer.
We must work
together if we are to reduce the burden of cancer in our city. To that end, the
DC Cancer Coalition, a broad partnership of public and private institutions,
organizations, and advocates has developed a comprehensive, coordinated plan
with specific strategies to have a greater impact on cancer in the District.
Our institutions are committed to work collaboratively together and with the
cancer community in implementing the Plan, and we invite all other concerned
citizens and organizations to join us.
Please become familiar with the Plan. Talk with your colleagues.
Then identify how your institution, agency, or organization can use the Plan as
a guide for your own activities and consider what role you can play in
implementing strategies for the greater good of the citizens of the
District of Columbia
. In
the days ahead, leaders of the Cancer Plan will reach out to you and seek your
ideas, insight, and assistance. We hope you will respond. The lives of many
citizens in our community depend on the efforts of all of us.

Creating
the District’s First Cancer Plan
In
2001, because the
District of Columbia
has the
highest cancer mortality rate in the
United States
, the DC Department of
Health (DOH) created the DC Cancer Control Coalition to serve as a partner in
addressing
comprehensive cancer control and prevention. In 2003, the Department of Health
received initial funding from the Centers for Disease Control and Prevention to
begin this process.
The
Coalition is a partnership of medical centers, nonprofit organizations,
academic and research institutions, community groups, advocates, professional organizations,
and others. We have worked together for four years to produce the District’s
first Cancer Plan—an analysis of the present environment, a blueprint to reduce
the number of new cases of cancer and the number of cancer-caused deaths and to
improve the quality of life for cancer survivors in the nation’s capital.
As
you will see, the need is urgent.
Cancer
in the District: Portrait of Inequity
Our
city of 560,178 residents—the nation’s capital—has the highest cancer mortality
rate per population in the
United
States
. In 2005, according to American
Cancer Society
projections, about 2,820 individuals will be
diagnosed with cancer in the District, and 1,170 will die of the disease.
Cancer is the leading cause of death in DC among those 85 years and younger.
These
high rates exist despite having four cancer centers, a total of 11 hospitals,
and an abundance of excellent cancer care services. But many of these services
are neither accessible nor affordable for many of DC’s citizens—the poor and
medically underserved (uninsured and underinsured), most of whom are Black or
Hispanic.
Inequitable distribution of cancer care plays a major role in the city’s high
mortality rates, and in every aspect of cancer control: screening, early
detection, treatment, survivorship, palliative and end-of-life care.
About 58% of the District’s population is Black, 27% is
White and 3% Asian. About 10% of the population is of Hispanic origin (some
self-identifying as White, and some as Black). Another 2% describe themselves
as “two or more races or other.” [Thomson Medstat©2004] The Hispanic population
is the city’s fastest-growing and includes many of the poorest residents.
Hispanic residents are the least likely to have health insurance of any kind.
Key
factors influencing the high rates of cancer incidence and mortality include
• Many of the District’s residents—about 300,000—live in a “Health Professional
Shortage Area (HPSA).” This includes many of the working poor. These residents
lack what is called a “medical home,” a primary care provider who knows their
health history and is a reliable source of routine medical care. The single
largest determining factor in the use of cancer services, from prevention
through treatment and follow-up, is having a primary care physician who makes
recommendations and provides assistance in navigating the health care system.
The DC Primary Care Association (DCPCA) links this lack of adequate primary
care to poorer health outcomes, higher health care costs, and overused, overcrowded emergency rooms.
“Because people can’t find a doctor,”
explains DCPCA, “they delay care, escalating the severity of illness to crisis
and contributing to high disability rates.”
• Deaths from breast, cervical, colorectal, and
prostate cancer can be avoided or decreased through screening procedures.
However, facilities for cancer screening are few and far between in the
District’s poorer neighborhoods. Most screening resources are located north of
the
Anacostia
River
, and many of the District’s
poorest neighborhoods, where many of the cancer deaths occur, are southeast of
the river. Remote locations for screening present a formidable barrier to
participation.
• Additionally, the
District underfunds
screening programs for breast and cervical cancer. Project WISH, a CDC-funded
screening program for breast and cervical cancers, has been hampered by
problems related to management, reimbursement of providers, tracking, and
patient follow-up.
At this time, there is also no District funding allocated, and there are no
systemic programs for, prostate and colorectal cancer screening.
• In addition to its many hospitals and
medical centers, the District prides itself on having many public and private
health care clinics. However, the clinics are only loosely linked to each other
and to other parts of the health care system. It can take people with symptoms
a long time to get a clinic appointment, and a patient who does manage to get
screened and receives a screening result indicating possible cancer may not get
appropriate
follow-up care, medications, counseling, rehabilitation and services like
transportation.
• It can be very
difficult for any patient—rich or poor, highly educated or uneducated—
to navigate through the health care labyrinth in the District. When a diagnosis
of cancer is compounded by factors such as limited English proficiency,
poverty, cultural
or cognitive barriers, lack of reliable transportation, and considerable
distances to travel for care, it is not difficult to understand that people
become overwhelmed and may elect to drop out of all or part of the health care
system that exists, and not complete cancer treatments.
• The DC Cancer
Registry has had difficulty collecting sufficient data on cancer in the
Hispanic community, despite the fact that this segment is the City’s
fastest-growing population. This data is needed to design effective measures
for cancer control in the Hispanic community.
• The DC HealthCare Alliance, in
partnership with the DC Department of Health, private and nonprofit health
clinics, offers low-income residents access to an array of health care
services. Because the
Alliance
is extremely underfunded, it has never enrolled all eligible people.
Specialists often avoid participating in its network because the
Alliance
reimburses
physicians and hospitals very slowly and far below the actual cost of care (15
cents on the dollar). Hospitals and physicians who serve
Alliance
or Medicaid patients in the
emergency room are not reimbursed at all. The District’s hospitals
annually must absorb millions of dollars of uncompensated care—so much that
some hospitals now are refusing to treat
Alliance
patients. This is clearly a broken system that fails to serve DC’s neediest
patients with an array of illnesses—not only cancer—and meaningful reform is
urgently needed.
• The Department of
Health reports that a number of steps have been taken to further integrate and
improve the Alliance and Medicaid, including appointment of a single Medical
Director, adoption of HEDIS (Health Plan Employer Data and Information Set)
measure reporting, implementation of new waivers, use of managed care
organizations, and dual use of Income Management Administration. The DOH
further notes that the department is in the midst of a major reform of the DC
Alliance that will take effect in 2006.
• It should be noted
that, unlike most states, the
District
of Columbia
fails to spend any tobacco settlement
funds received on health care and cancer services. This has left the city with
almost no infrastructure with which to build an effective cancer control and
prevention program.
The bottom line is that many of the
District’s neediest residents cannot or do not take advantage of available
cancer care in the District. They struggle to navigate the convoluted health
care system, the programs designed to provide care often fail to do so, there
is no substantive public health structure—and as a result people are dying of
cancer at high rates, despite living near highly sophisticated cancer care
facilities.
Plan preparation and components
The DC Cancer Coalition workgroups (including physicians,
public health experts, community leaders and others) have developed specific
research-based chapters
of the Plan. In each chapter, we assess the cancer burden, address current
resources, identify gaps in care, and set forth prioritized recommendations
that we believe will set the District and the health care community on course
to correct the problems presented.
In the chapters that follow, we present separate discussions,
goals, objectives and strategies for the following areas: Access to Care,
Cancer Prevention, Smoking-Related Cancers, Head and Neck Cancers, Breast
Cancer, Gynecologic Cancers, Colorectal Cancer, Prostate Cancer, Pediatric
Cancers, Palliative Care, Cancer Survivorship, and Cancer Rehabilitation. In a
separate document, we will also publish a resource guide for the region, The
Community Resource Directory for Cancer Survivors and Caregivers.
What Must Be Done: Implementation
The next step in addressing cancer control and prevention is
to use the Cancer Plan to move the District forward. We understand that
bringing the Cancer Plan to life is the work of years, and that with individual
and collaborative actions must come ongoing evaluation and mid-course
corrections as needed to respond to the changing
environment around us. At every step of the way, it will remain important to
seek input from stakeholders throughout the city on progress and problems.
Some of the work ahead will require examining public policy
that affects cancer in DC. Other priorities demand new avenues of collaboration
among the city’s health care providers, and securing the funding necessary to
make collaboration possible and effective. These tasks are formidable, but the
Coalition’s members are committed to doing everything in our power to relieve
DC’s heavy burden of cancer incidence and mortality. Behind the statistics is
great human suffering, and that suffering must be alleviated.
Almost every part of cancer care as it relates to the
medically underserved majority of residents in the
District of Columbia
is broken and a clear
path for change must be taken if lives are to be saved.

Developing
a Cancer Control Plan
for the
District of Columbia
To address the problem of very high rates of cancer in the
District of Columbia
, in
2001 the DC Department of Health (DOH) created the DC Cancer Coalition. The
Coalition was born when the DOH and other stakeholders attended a leadership
institute sponsored by the Centers for Disease Control and Prevention, the
American Cancer Society, the National Cancer Institute, and the
American
College
of Surgeons. There we learned
more about how to develop and implement comprehensive cancer control programs
that integrated partnerships, communication, and collaboration. In 2003 the
Department of Health received an initial grant for cancer planning from the
CDC—and the Coalition began its work.
Committed to addressing the District’s very high cancer
rates—the highest cancer death rates in the nation—the Coalition is a
broad-based partnership, including medical centers, nonprofit organizations,
academic and research institutions, community groups, advocates, professional
organizations, and others. All have an interest in cancer prevention and
control. Our objective has been to develop a comprehensive cancer control plan
that could serve as a blueprint for reducing the number of new cancer cases in
the District and the number of deaths from cancer. We have followed the CDC’s
model of creating “an integrated coordinated approach to reducing cancer
incidence, morbidity, and mortality through prevention (primary prevention),
early detection (secondary prevention), treatment, rehabilitation, and
palliative care.” The Plan is designed to
• Identify the strengths
and weaknesses of current cancer prevention and control efforts in DC
• Identify barriers that
hinder prevention and control efforts and offer strategic options for
surmounting them
• Provide a set of goals
and objectives for cancer control based on a review of DC data
• Identify strategies
for meeting those objectives.
Disparities in cancer care in DC:
Demographics and access
The District is home to an abundance of medical care
facilities and providers, but equal access to cancer care services is
significantly undermined by the physical location of those providers. Access to
cancer screening, treatment, and follow-up care is, in some measure, influenced
by where a District resident lives.
Geographically, the District is divided into four quadrants:
northwest, northeast, southwest, and southeast. Politically, it is divided into
eight wards (see Figure 1). Wards 1, 3, and 4 are in the northwest quadrant;
Ward 2 straddles northwest and southwest; Ward 5 is mainly in the northeast
(and a bit of northwest): Ward 6 is in northeast, southwest, and southeast;
Ward 7 is in both northeast and southeast; and Ward 8 is in the southwest and
southeast quadrants.
Many cancer-related
health care facilities are located in northwest
Washington
(in Wards 1, 2, 3, 4, and parts
of Ward 5). There is just one
full-service hospital located beyond the
Anacostia
River
(Wards 7 and 8), serving
20% of the District’s population. For those dependent on public transportation,
especially those weakened by cancer, it can be difficult and exhausting to
reach a hospital in another part of the city. One District hospital,
Providence
, is in the
northeast quadrant. Another, Greater Southeast Community Hospital, is in
southeast. The other nine—Children’s
National
Medical
Center
,
George
Washington
University
Hospital
,
Georgetown
University
Medical
Center
,
Howard
University
Hospital
,
National
Rehabilitation
Hospital
,
Sibley
Memorial
Hospital
, Veterans’
Affairs
Medical
Center
,
Walter
Reed
Army
Medical
Center
,
and the
Washington
Hospital
Center
—are all in the
northwest. All four
cancer centers—
Georgetown
, George
Washington, Howard and
Washington
Hospital
Center
—are
located in the northwest.
The inequitable distribution of infrastructure for cancer
care in the District is reflected in the city’s cancer incidence and mortality
rates. Disparities in access to care and in the quality of care are seen in every aspect of
cancer control: screening, early detection,
incidence, treatment, quality of care, and survival. Disparity issues are
considered in nearly every chapter of the Cancer Plan. We expect implementation
of the Plan to facilitate the creation of an effective local infrastructure for
reducing these disparities, for reducing high cancer incidence and mortality
rates in the District, and for improving the quality of life of cancer
survivors—wherever in the city they may live.
As of 2004, DC’s population
was 58% Black, 27% White, and 3% Asian. Another 2% describes themselves as “two
races or other.” About 10% of the population is Hispanic (some self-identifying
as White, some as Black). The Hispanic population, which is the fastest growing
segment in the city, is located mainly in Wards 1 and 4.
Although the city’s population is
distributed roughly equally among the eight wards, income distribution is
unequal. A
significant number (roughly 147,000 or 26%) of residents have household incomes
below
$20,000 a year. The high cost of living in
Washington
places households earning less
than $20,000, especially those with earnings below $10,000, in extreme poverty.
Average
per capita income is highest in Ward 3 ($68,477) and lowest in Ward 8 ($14,137).
Similarly, average household income is
highest in Ward 3 ($134,506) and lowest in Ward 8 ($38,754).
Almost 300,000 Washingtonians—
22% of those older than 25—do not have a high school diploma. The
highest number of people with college degrees is reported in Ward 3 (79%), and
the lowest in Ward 8 (8%).
Developing the Cancer Plan
To develop the Plan, the Coalition created
multidisciplinary workgroups (physicians, public health experts, community
leaders, survivors, representatives of advocacy groups, nurses, social
workers). Each workgroup developed a chapter of the Plan, reporting its
findings to the full Coalition. The Coalition developed a list of objectives
for cancer control based on a review of research data and identified strategies
for achieving those objectives. We carefully evaluated the cancer burden in the
District, analyzed tumor registry data on incidence and mortality, reviewed
national data on cancer, catalogued existing resources for screening and early
detection, considered the impact of disparities on health care, and sought out
community leaders for advice and direction. We looked at modifiable and
nonmodifiable risk factors for specific cancers, discussed control strategies
based on evidence, examined approaches to health communications, categorized
clinical services, compared survival rates, and built partnerships.
The Plan’s primary focus
was on strategies known to reduce the number of cases of cancer and to reduce
deaths from the disease. Recommendations for cancer screening were based mainly
on those of the American Cancer Society, although recommendations from the
Preventive Services Task Force and other professional organizations were also
reviewed. A secondary focus was to identify resources to assist people with
cancer, including support groups, educational programming, and other community
opportunities. These resources are presented in a separate publication, the
Community Resource Directory for Cancer Survivors and Caregivers.
Based on data about the burden of cancer and available health
care resources in the
District, we established cancer site priorities
for DC’s Cancer Plan of breast, cervical, colorectal, smoking-related cancers,
head and neck cancers, and prostate cancer.
Priorities were based on scores of four
factors:
• The extent of a
particular cancer burden
• Whether intervention
was important
• Whether intervention
was feasible
• Whether intervention
would have a
measurable impact (that is, reduce
incidence and/or mortality rates).
The burden of deaths from smoking-related cancers, for
example, is sizable. Effective intervention is feasible, and its impact would
be large and measurable. Similarly, the burden of prostate cancer is the
District is both heavy and inequitable, and effective intervention is solidly
feasible and measurable. Breast cancer interventions are a priority because the
cancer burden is heavy, mammography is
a fairly effective screening tool, screening
reduces mortality, and effectiveness is
measurable. Interventions to deal with
colorectal cancer, a major problem in the
District, are more difficult. The best way to intervene is through a citywide
colonoscopy program. This would be very expensive and
is therefore more difficult to implement—
although efforts to educate physicians and patients about the value and
importance of screening can have a positive effect.
For each type (or anatomical site) of cancer, we looked at
risk factors, gaps in and barriers to cancer control, and the best-known
prevention and control measures, before we identified goals, objectives, and
strategies for that type of cancer. We also addressed access to care, what to
do about smoking-related cancers, how to support and improve the quality of
life for cancer survivors, how to improve palliative and end-of-life care, and how to integrate cancer rehabilitation
services into overall cancer care.
The chapters were reviewed for accuracy
and completeness by physicians and other health care professionals not
associated with the Coalition, as well as by lay consumers.
The Coalition is deeply indebted to these reviewers for time-consuming efforts
that, they surely know, will benefit many. As part of its mission, the
Coalition will review the Plan
regularly and modify priorities to reflect new data, new scientific knowledge,
and the
availability of more or different resources. We have included an evaluation
component, so we can measure progress.
In the summer 2005, the DC Cancer
Coalition held a series of five town hall
meetings in neighborhoods around DC to introduce the Plan, to listen to
residents’ thoughts and reactions to the Plan and to encourage residents to get
involved in fighting cancer in the District. The Department of Health also held
a series of Health Disparities Town Halls at which they announced the Plan and
invited residents to become involved in implementing the Plan.
The Coalition is pleased to present this Plan to the
citizens, community leaders, and city authorities of the
District of Columbia
. We
look forward to constructive comments
and approval of the Plan’s objectives and
strategies, and to creating innovative,
speedy, and effective actions for the next phase of our work—implementing the
Plan. The District now joins 27 states that have
developed cancer control plans.
Great therapeutic developments over the past few decades have
led to more effective and less disfiguring cancer treatments. But not every
American has benefited from this
progress, as evidenced by higher cancer incidence rates and lower survival
rates in certain populations. Poor people lack access to health care and are
more likely than others to die of cancer, reported the American Cancer Society
in its 1989 report, Cancer in the Poor.
Moreover, poor people are less likely to be covered by health insurance and
often do not seek care if they are unable to pay for it.
In 2004, the number of insured nationally rose to 45.8
million, compared to 45.0 million in 2003 and 39.8 million in 2000. A
continuing decline in employer-sponsored plans is a major cause. The percent of
working adults (18 to 64) who were uninsured climbed from 18.6% in 2003 to 19.0
percent in 2004, an increase of more than 750,000 people. Nationwide, African
Americans (20%) and Hispanics (33%) were much more likely to be uninsured than
White, non-Hispanic people (11%).
Reducing cancer incidence and mortality
rates in the District of Columbia will require eliminating barriers to primary
and cancer
care for all DC residents, but especially
the medically underserved—the poor, the
uninsured, and the culturally isolated. Only
with accessible, affordable personal health care services can DC residents hope
for the best possible health outcomes.
Barriers to care in the District
Demographics—insurance coverage, poverty,
education, race, language, age, and gender—
explain many DC residents’ failure to get adequate health care. Lack of
knowledge and information about sound health practices may also keep many
residents from getting the care they need.
Whether DC
residents have access to good health care often depends largely on whether they
have health insurance coverage. Lack of insurance
or underinsurance (lack of full coverage or limited access to health care) is
the most significant factor contributing to disparities in cancer care.
In 2004, the number of insured nationally rose to 45.8
million, compared to 45.0 million in 2003 and 39.8 million in 2000. A continuing
decline in employer-sponsored plans is a
major cause. The percent of working adults (18 to 64) who were uninsured
climbed from 18.6% in 2003 to 19.0% in 2004, an increase of more than 750,000
people. Nationwide, African Americans (20%) and Hispanics (33%) were much more
likely to be uninsured than White, non-Hispanic people (11%).
Proportionately, more DC
citizens are covered by employer-sponsored insurance than the national average
because of the concentration of federal agencies and offices in the District.
Of DC’s non-elderly adults, 70% have employer-
sponsored or self-paid insurance, 11%
have Medicaid, 13% have no insurance and 5% fall into an “other” category. The
number of uninsured non-elderly adults in DC (74,200) can swell by thousands
throughout the year, as some residents temporarily lose their health insurance
during a hiatus in employment.
General
Hospital
closed, to
improve access to care for the uninsured. The
Alliance
suffers from insufficient funding
and an inability to contract with specialists, such as oncologists, because of
very low rates of reimbursement and very long delays in providing reimbursement.
Who are the uninsured?
• In 1999, 60% of DC
adults may have
qualified for Medicaid or DC HealthCare
Alliance coverage, based on income. (Adults with children are eligible for
Medicaid if their income falls below 200% of the federal
poverty level.) DC Medicaid also provides some coverage for low-income,
non-parent adults.
• In 1999, 36% of DC
adults over age 65 had income that fell below 200% of the federal poverty
level, possibly qualifying them for Medicaid.
• The number of Medicaid
enrollees in DC
represented 81% of the eligible population
in 2001, according to the Centers for
Medicare and Medicaid Services.
• Many of the “working
poor” are uninsured: 72% of uninsured DC residents are part of family
households in which at least one household member works part- or full-time, and
48% of the uninsured have family
members who work full-time, year-round.
• The largest group of
uninsured adults (29,500) is 30-to-49-year-olds, but another age group, the
19-to-29-year-olds, has the greatest percentage of uninsured. The two groups
with the most uninsured members are Hispanic residents (about 13,800
residents, or 33.4% of the local Hispanic population) and non-Hispanic Blacks
(with 50,200 residents, or 16.7% of non-Hispanic Blacks), as Table 1 shows.
• Undocumented aliens have no health
insurance. Although they can receive free or low-cost health care at a
community health center, the center will ask them to apply for Medicaid so it
can recover some of its costs. Undocumented residents are reluctant to apply
for a public program because it
might mean having to divulge reportable information. If an undocumented alien
visits the emergency room, he will be served. If he has to be admitted to the
hospital, the admitting physician will have to follow the patient at no charge.
• In the year 2000, 13%
of DC residents worked for small-business employers, who were less likely to
offer insurance because
of the high cost of premiums. About 63%
of DC residents worked in service and retail positions that did not offer
health insurance benefits.
• Some low-wage earners
have to forfeit health insurance benefits because they cannot afford the
employee’s share of the premium.
• About one-third of
DC’s non-elderly adults went without health insurance for all or part of the
two-year period from 2002 to 2003. Adults with no insurance and those with
Medicaid are more likely than adults with
private health insurance to report that they are in poor to fair health (18%,
29%, and 7%, respectively).
• Residents with some
health insurance may not have coverage for pharmaceuticals,
durable medical equipment, nutritional
supplements, sub-acute care, long-term care, or mental health services.
Medicare
is the largest health insurance program with only partial coverage.
Race
and ethnicity themselves are not
barriers to primary and cancer care, but
minority status associated with poverty or
with negative perceptions of the health care system may affect outcomes. As
Mandelblatt and colleagues observe, some Hispanic and Black populations are
either fatalistic about cancer or are too preoccupied with day-to-day survival
to seek early detection or treatment.
Levels of education and literacy, especially health literacy,
are important aspects of social status that affect health outcomes. The
Annals
of Internal Medicine reported that
literacy skills predict an individual’s health
status more strongly than age, income,
employment status, race, or ethnicity. Poor literacy impedes people’s ability
to learn about disease prevention, understand disease-
related information, follow physicians’
instructions, take medications properly, and self-manage health care.
Socioeconomic status is also a factor.
Regardless of other factors, people in lower socioeconomic groups report less
use of
cancer screenings and are diagnosed with cancer at later stages than those in
higher socioeconomic groups—even in Canada and Finland, countries with
universal health care coverage.
Socioeconomic status also appears to affect the quality of
care. People from lower socioeconomic groups also have poorer survival rates,
possibly because of such factors as inadequate staging evaluation and delays in
treatment. Regardless of treatment, cancer patients from lower socioeconomic
groups with advanced cancer report less symptom control and less use of
palliative and supportive care services (especially hospice) than patients from
higher socioeconomic groups.
The percentage of uninsured in DC (13%) is lower than the
national average (19%), but the
percentage of residents who live in
poverty (20.3%) is higher than the national average
(12.4%). Although the city’s population is distributed
roughly equally among eight wards, income and relative insurance status are
distributed unequally (see Table 2).
Unfortunately, the poverty gap—the gap
between the wealthy and poor—is as wide in DC as in any other major
U.S.
city, and
the gap is widening. The average income of DC’s wealthy families grew 38% in
the 1990s; the income of poor families grew only 3%.
The adult populations in DC most likely to
be uninsured are poor, male, and Hispanic or Black. The Hispanic population is
particularly vulnerable, having the highest uninsured rate, being poorer than
non-Hispanic Blacks or Whites, and having worse health indicators than both
groups.
Residents of the
District of
Columbia
, many of whom are recent
immigrants or temporary residents, come from more than 150 countries. This
enriches the culture but creates linguistic challenges. A health care center,
despite federal requirements to provide qualified interpreters, often cannot
provide interpreters for every language. Even if an interpreter is available,
the interpreter may know a word but not in a medical context, and the health
care provider may not appreciate the cultural nuances of each phrase or topic.
What’s more, people from some countries may consider the direct and candid
U.S.
style of
communication too forward or impolite. There is, therefore, sometimes a reduced
chance of clear
communication.
Although 77% of all cancers are
diagnosed in people 55 and older, older people may not realize their risk of
cancer,
may ignore symptoms, and may suffer from cognitive impairment and other medical
conditions. And proportionately more of the elderly are poor and underinsured.
Any of these factors may limit older people’s pursuit of early detection or
cancer treatment. And as the senior population grows, age will become a more
significant barrier to good primary and cancer care. Heavy concentrations of
adults 55 and older live in Wards 3, 4, 5, and 7
(see Table 3).
Evidence shows that men seek
routine preventive medical care less often
than women, but research has shown
practitioner bias in screening men for cancer more often than women.
People immigrating to the District
from other countries bring with them a host of customs, attitudes, and health
care practices that can affect their health care here. Poor immigrants,
especially when confronted with a complex health care system managed in a
language different from their own, may simply avoid or minimize contact with it
except in emergencies, and rely on practices they know from their own cultures.
Similarly, the pressure of urgent daily priorities such as food,
employment, transportation, education,
housing, and safety may mean that cancer screening for early detection becomes
a
relatively low priority.
Barriers to screening or
cancer care can be as basic as not
having transportation to an appointment
with a physician or to purchase essential
medications. Many patients do not have their own private means of
transportation and their family members may work or may also not have a means
of transportation. Public transportation is widely available in the District,
but it often requires a far greater commitment of time—time away from work and
from family—than arriving by private automobile would, for
example. When the requirements of time
are combined with the exhausting side effects of cancer treatment,
transportation becomes
a significant barrier. Moreover, demand-
responsive transportation for cancer patients and disabled persons is limited
in the District, and some volunteer drivers of agency
transportation programs and taxicabs will
not travel into neighborhoods they perceive
as dangerous.
Barriers to care from primary care and cancer care providers
Problems among primary care providers and oncologists may
limit some patients’ access to good health care.
The greatest predictor of patient
compliance with cancer screening
is a physician’s recommending a cancer screening test. But whether a primary
care provider recommends such a test may be
affected by:
• The provider’s biases
and beliefs about screening and treatment effectiveness
• Insufficient
knowledge, training, or skill (performing a clinical breast exam, for example)
• A dearth of culturally
sensitive resources
• Forgetfulness and lack
of time
• Concern about the
patient’s other acute
illnesses
• Conflicting screening
guidelines from
professional and health organizations
• Concerns about patient
acceptance
• No chance of
reimbursement
• Logistical or
organizational barriers
• Prejudices based on
age, race, gender,
or sexual orientation
• Inadequate
communication skills.
As of 2001, DC had the highest
physician-to-population ratio of any state, but most of those physicians do not work in low-income neighborhoods
(see Table 4 for location of clinics by ward). According to the Bureau of
Primary Care of the U.S. Department of Health and Human Services, 300,825 DC
residents (52% of the total population) live in federally designated primary
care Health Professional Shortage Areas (HPSAs) and 173,228 (30%) live in
federally designated Medically Underserved Areas (MUAs). Areas designated HPSA
and MUA tend to include many poor households and homes of racial and ethnic
minorities.
Many of the 300,000
District residents identified as living
in a Health Professional Shortage Area do
not have a “medical home”— a primary care provider who knows a patient’s health
history and is a reliable source of non-emergency medical care. The DC Primary
Care
Association (DCPCA) has linked the lack of adequate primary care in DC to
poorer health outcomes, higher health care costs, and overused and crowded
emergency rooms. “Because people can’t find a doctor,” explains the DCPCA,
“they delay care, escalating the severity of the illness to crisis and
contributing to high disability rates.”
The DC HealthCare Alliance has difficulty enrolling and maintaining oncologists
and other specialists, who feel the insurer’s reimbursement rates are too low
and slow.
Problems intrinsic to the local health
care system
When
DC General
Hospital
closed in 2000,
its patients were transferred to DC’s
remaining hospitals. All the hospitals in DC accept Medicaid and DC HealthCare
Alliance patients. When hospitals serve these
populations, they are required to serve them in the emergency room as well.
Seven percent (7%) of DC residents identify the emergency room as their primary
source of medical care. A greater proportion of uninsured DC residents
use the emergency room as their regular source of medical care than do insured
residents.
DC prides itself on its many private and
public community health centers that provide excellent primary care. The
weakness of the community health centers is that they are only loosely linked
to each other and to other parts of the health care system for services such as
diagnostic follow-up, cancer treatment, behavioral health, transportation,
counseling, pharmacy or hospital services. As a default, patients may use hospital
emergency services that are more expensive and more traumatizing to the
patients.
Timing and follow-up are also issues in
health care centers, where it often takes too much time to arrange for
diagnostic follow-up, treatment, and post treatment care. For lack of equipment
and expertise to handle billing adequately, community health centers have at
times had difficulty submitting timely program and financial information to
contractors and health plans. Project WISH, the DC Breast and Cervical Cancer
Early Detection Program, lost funding temporarily because it did not receive
timely reports from community health centers that are Project WISH provider
sites.
On the other hand,
community health centers often have difficulty retrieving reports from
specialists, especially those in hospitals, on
Alliance
and
Medicaid patients they serve. There is controversy about who owns the
information, suspicion about how the information will be used, and little
cooperation among some health care providers. There is a strong sense in
general that the community health centers want to strengthen their links to
hospitals, the DC HealthCare Alliance, specialty providers, and the DC
Department of Health.
Even an educated person, astute about health care, can have
trouble navigating the labyrinth of health care resources, regulations, and
procedures in the
U.S.
health care system,
as well as complying with instructions from multiple physicians. Sometimes a
family member or friend has the time and ability to help a
patient maneuver through the health care
labyrinth and even to serve as the patient’s advocate. But add a complex
medical condition and/or language, cultural, and financial barriers and the
patient, overwhelmed, may drop out of part or all of the health care system.
Professional or lay “patient navigators” can help a patient
through the system if a competent family member or friend cannot. Especially
with medically underserved and vulnerable populations, patient navigation has
been effective in improving access to good care. A few community health centers
and DC’s Project WISH successfully use patient navigators. But the need for
patient navigation far outweighs current resources.
After
DC General
Hospital
closed, a program called the DC
HealthCare Alliance was created to offer health care to uninsured DC residents
whose income is 200% of the federal poverty
level or less and who are not eligible for Medicaid or Medicare. In the DC
HealthCare Alliance, through a partnership with the DC Department of Health,
private and nonprofit community health centers offer access to inpatient
hospital care, outpatient medical care (including preventive services),
emergency services, prescription drugs, rehabilitative services, home health
care, dental services, specialty care, and wellness programs
(including pre- and post-natal care).
But the
Alliance
faces certain challenges:
• Because the city
chronically underfunds the
Alliance
,
it has never been able to enroll all eligible persons.
• It added no additional
community health centers or physicians to DC’s medical
infrastructure to serve the eligible population.
• It has had difficulty
enrolling specialists in its network of physicians because of low and slow
reimbursements.
• It does not reimburse
physicians who serve DC HealthCare Alliance or Medicaid patients in the
emergency room.
• It reimburses
hospitals and physicians slowly and at far below the actual cost of care (15 cents
on the dollar), so hospitals have to absorb millions of dollars in
uncompensated care each year. Providers have little incentive
to provide additional services to patient groups that do not generate revenue.
Another support service
for District residents is the Archdiocesan Health Care Network, whose mission
is to connect uninsured patients seen in their clinics with appropriate
specialists and tests. This network has several hundred physician-specialist
volunteers who will see patients from the clinics for workups and in some
instances will provide surgery and follow-up care.
DC is
fortunate in having eleven hospitals that
provide cancer care.
Lombardi
Cancer
Center
(at
Georgetown
) has been designated a comprehensive
cancer center by the
National Cancer Institute. Other cancer
centers include
George
Washington
University
Cancer
Center
,
Howard
University
Hospital
Cancer
Center
,
and the Washington Hospital Center Cancer Institute. Three hospitals have
medical schools and four are teaching
hospitals. The cancer programs of eight
hospitals are approved by the Commission
on Cancer of the
American
College
of
Surgeons. Because of the quality and quantity of hospitals in DC, numerous
cancer-related clinical trials offer state-of-the art cancer care, potentially
improving access to quality care for the medically underserved and reducing
disparities in cancer care among racial and ethnic groups. Historically,
however, minorities and females are severely underrepresented
in clinical trials, for various reasons. The
literature has identified the barriers to minority participation in clinical
trials and strategies
for overcoming these barriers. There is no
legislative mandate for insurers in DC to cover the routine costs of patient
participation in clinical trials.
Half of the
community health centers in DC offer early morning hours, 38% offer evening
hours, and one-third offer Saturday hours. Ward 1 has the most community health
centers; Ward 4 has none. In the District, there are
• Three federally
qualified health centers (FQHCs) with 28 sites
• Three
hospital-sponsored health centers
with 14 sites
• Eleven private,
nonprofit centers with 12 sites
• Twelve uncategorized
clinics.
In the fall of 2003 the DC Primary Care
Association reported that 52% of the FQHCs, 80% of the hospital community
health
centers, and all of the private nonprofit
community health centers could not meet
current needs with existing resources.
Despite the District’s very high cancer incidence and mortality
rates, the DC Department of Health underfunds screening programs for breast,
cervical, and prostate cancers and provides no funding for screening for
colorectal cancer. Most screening resources are located north
of the
Anacostia
River
. Many of the poorest DC
neighborhoods are southeast of the
river. In Southeast DC, there is only one
mammography facility: the
Capital
Breast
Care
Center
. The remote
location of most screening sites is a barrier to increasing cancer screening
rates, especially for women who have difficulty
taking time off from work or arranging for transportation and child care.
Two
organizations in DC (Rx4DC.org and DC
Pharmaceutical Resource Center) help
uninsured residents identify and apply to
pharmaceutical companies that provide free medications to residents who are low
income,
are uninsured, or receive Medicaid. One
problem is that pharmacies in some low-
income neighborhoods do not stock
prescription pain medications for fear of
burglary related to substance abuse. This means that cancer patients who need
these medications face additional hurdles obtaining relief.
Progress
The Department of Health reports that a
number of steps have been taken to further integrate and improve the Alliance
and
Medicaid, including appointment of a single Medical Director, adoption of HEDIS
measure reporting, implementation of new waivers, use of managed care
organizations, and dual use of Income Management Administration. The DOH
further notes that the Department is in the midst of a major reform of the DC
Alliance that will take effect in 2006.
Meanwhile, the DC Primary Care Association, with significant
support from the DC
Department of Health, has launched a
Medical Homes Initiative to strengthen the infrastructure of the community
health
centers network. The citizens who
developed the DC Cancer Plan wholly
support these efforts, including the DC
Primary Care Association’s plans to establish a coordinated, citywide database
to track patient information.
GOAL: To improve access to primary
and cancer care for DC residents.
1)
Create a coordinated patient navigation system by 2008.
• Seek funding for coordinated patient navigation in hospitals and community
health centers.
• Develop a coordinated patient navigation system.
2)
Establish affiliation agreements between the community health centers,
hospitals,
and health care providers for diagnostic
follow-up and treatment by 2007.
• Facilitate negotiation of these affiliation agreements.
3)
Improve access to public transportation for cancer patients by 2010.
• Work with the Washington Metropolitan Area Transit Authority (WMATA) to expand
its
demand-responsive system.
4)
Increase the participation of eligible minority residents in cancer-related
clinical
trials by 15% by 2010.
• Advocate for legislation requiring insurers to cover routine patient costs for
clinical trials.
• Update health care providers on clinical trials and encourage patient
referrals.
• Launch an awareness and recruitment campaign focused on racial and ethnic
populations, particularly Blacks and Hispanics.
5) Educate consumers about access to
cancer screening, care, and other services
by 2010.

Facts in brief
There is a growing body of epidemiological
evidence suggesting that factors
contributing to the development of cancer (as well as undermining overall
health) include:
• Smoking and
overconsumption of alcohol (especially combined)
• Overexposure to
ultraviolet light (through sunlight or tanning salons)
• Overconsumption of red
meat, especially when charred
• Overconsumption of fat
and sugar
• Consumption of food
cooked with harmful fats.
• Insufficient
consumption of fruits, vegetables, and whole grains—rich in vitamins,
antioxidants, and minerals that may help slow or prevent the development of
cancers.
• Too little physical
activity.
Cancer has now surpassed heart disease as the nation’s number
one killer for persons age 85 or younger. Coronary heart disease
declined significantly after 1973, largely through changes in people’s
behavior—
and it is not unreasonable to think that a
similar decline in cancer incidence could occur if individuals changed to
behaviors that appear to help prevent the disease: sound nutrition, no smoking,
maintaining reasonable weight, minimal or no alcohol consumption, adequate, regular
physical activity, and limited exposure to the sun. By some estimates, poor
nutrition, physical inactivity, and obesity together
account for roughly a third of all cancer deaths, and the use of tobacco
another third.
Prevention eliminates many problems and costs down the line, but it must be
started early. The best way to prevent lung cancer, for example, is never to
smoke. An ounce of prevention truly is worth a pound of cure—
reducing illness, prolonging a healthy life, and maintaining a satisfactory
quality of life.
American health has declined as Americans have shifted
increasingly to a diet of foods high in fat, sugar, and refined grains—the
staples
of fast food restaurants that serve oversize portions to vast numbers of
Americans. Almost a third of all children and teenagers consume fast food on a
typical day.
Current dietary recommendations include minimal fats and red
meat and plenty of fruits, vegetables, and whole grains. Fruits and
vegetables are probably protective because
of their fiber content, micronutrients, and
colorful phytochemical compounds, such as the lycopene in tomatoes, the folates
in leafy green vegetables, and the flavonoids in citrus. Not all valuable
dietary factors have been
isolated, so vitamin supplements may not be as valuable as whole foods.
The type of fat
consumed matters to general health, as well. Authorities recommend that foods
be prepared with such fats as olive oil, canola oil, and safflower oil.
Diets high in fruits, vegetables, and whole
grains reduce the risk of cancer—especially cancers of the colon, esophagus,
lung, and oral cavity. According to the National Cancer Institute’s “Eat 5 to 9
a Day for Better Health” Program, to reduce risk people should consume at least
five to nine servings a day of vegetables and fresh fruits, such as citrus,
yellow and green leafy
vegetables, soy products, and whole grain wheat products. A serving is
approximately that amount that fits in the palm
of the hand.
Surveys show that only 23% of adults and 21% of the young
consume the minimum five daily servings of fruits and vegetables recommended by
the National Cancer Institute. In
Washington
DC
, only 29.5% of adults and
21.3% of the young (in 2003) consumed at least five servings of fruits and
vegetables daily. Most people consume only two or three servings, and some none
at all (USDA, 1998).
Overweight as a risk factor
Lifelong eating behaviors develop early in childhood.
According to surveys conducted by the Centers for Disease Control, many DC
teens aged 12 to 17 are at risk or already overweight. Rates are especially
high among Hispanic and Black teens. Improving the
nutrition and physical activity practices of
children and adolescents is important for
promoting their long-term health.
Concern is growing about obesity’s effect on cancer, heart
disease, and stroke. Obesity rates among adults increased 75% between 1991 and
2001. In the last 20 years, the rates have doubled in children and tripled in
teens. The prevalence of obesity in men is the same among all racial/ethnic
groups, but in women the prevalence is highest among Blacks. More than half of
Black women over 40 are obese and 80% are overweight.
The American Cancer Society estimates that obesity accounts
for 14% of all cancers in men and 20% of those in women in the
United States
.
In the
District of
Columbia
in 2003, 52.4% of adults were identified as
overweight or obese, up from 50.5% in 1998—mirroring
nationwide trends that cut across both genders, all ages, and racial and ethnic
groups.
Obesity trends among
children will influence future rates among adults. Chances are that individuals
who are overweight as children or young adults will be overweight as adults. In
2003, 11.5% of DC high school students were overweight and
another 17.3% were at risk of becoming overweight. Rates are especially high
among Latino and Black teens.
Smoking and alcohol
In hundreds of studies, smoking has been
implicated as a cause of cancers of the lung and upper respiratory tract and is
also
associated with cancers of the large intestine, bladder, and pancreas.
Investigators estimate that 30% of all
U.S.
cancer deaths are
attributable to smoking.
Alcohol is known to interact with tobacco smoke in causing
cancers in the oral cavity, upper respiratory tract, throat, and
gastrointestinal tract. Alcohol and smoking have also been associated with
second cancers arising in the mouth and throat after a first mouth or throat
cancer has been treated. The most effective way to prevent cancers of the mouth
and throat is to avoid tobacco and drink minimal amounts of alcohol. Alcohol
has also been associated with cancers arising in the large intestine and
pancreas, although the evidence is not as strong as with cancers arising in the
head and neck.
There is also evidence that alcohol may increase the risk of
breast cancer in postmenopausal women.
Physical activity
Regular physical activity is an important
factor in maintaining healthy weight and body composition. DC residents are not
presently achieving recommended levels of regular physical activity. Survey
data show that in 2003 half of DC adults engaged in
moderate-intensity physical activity for 30 minutes or more at least 5 days of
the week. The association between physical inactivity and cancer is weak, but
physical activity has been shown to help prevent obesity, which is strongly
associated with cancer. Over half of DC residents are not participating in
enough physical activity to reap significant benefits.
There is a clear relationship between physical
activity and risk of colon cancer: the more physical activity, the lower the
risk of colon cancer.
Physical activity is also important in cancer treatment and
rehabilitation, helping to
improve mood, functional ability, quality of
life and reducing fatigue, body weight, and
the severity of some side effects.
The 2001 Shape of the Nation Report issued by the National Association for Sport and Physical Education strongly
recommended physical education for grades K through 6.
Although 95% of the lower grades have
physical education programs, they provide only about 40 to 50 minutes of
exercise a week. Middle and high school levels require a physical education
program, but the high school requirement extends only through grade 10,
providing for 60 fifty-minute classes for ninth grade and 120 fifty-minute
classes for tenth grade.
Physical education grades are included in the grade point
average. No other activity substitutions are allowed.
Avoiding overexposure to the sun
The most common carcinogen to which people are exposed is
sunlight (especially ultraviolet light). Overexposure to sun has been
associated with all forms of skin cancer, the most common cancer in humans.
Most skin cancers can be treated; only one, melanoma, is difficult to treat
and, when advanced, carries a high death rate. Since 1973 the rate of
melanoma has been increasing in adults, young adults, and teenagers—especially
among Whites. Presumably, the rising rate is the result of increased exposure
to ultraviolet light either through sunbathing, overuse of
tanning salons, and partial loss of the ozone layer. Frequent sunburns during
childhood may increase the risk of melanoma or other skin cancers that occur
years later. The routine use of sun block, which blocks ultraviolet light, is
strongly recommended. The best prevention, however, is avoiding too much sun
(especially in childhood) and not frequenting tanning salons.
Chemoprevention
Agents designed to prevent cancer or to inhibit growth of
precancerous lesions are under extensive investigation. The National Cancer
Institute, for example, is conducting a
clinical study to determine whether selenium and vitamin E can prevent prostate
cancer. Laboratory and clinical observations support the use of ordinary
aspirin for the prevention
of colon cancer, breast cancer, and lung
cancer. Aspirin use must be balanced against potential complications such as
internal
bleeding and allergic reactions, but daily use
of a single tablet of aspirin for life may reduce the risk of both cancer and
heart attacks.
Why well-known preventive measures aren’t common practice
Why don’t more people eat healthy diets, get enough exercise,
refrain from smoking and drinking too much alcohol, and generally follow
practices that would reduce the likelihood of cancer and other chronic
illnesses? There are several reasons. First, physicians fail to
convey information about preventive care to their patients, for many reasons:
they may not be trained or know enough to do so, they don’t have time, they
aren’t reimbursed adequately for time spent urging preventive care, and after
hearing conflicting professional recommendations may be skeptical about whether
they work. Second, many people don’t know about preventive measures or how to
implement them personally. This lack of understanding means people feel little
incentive to temper their eating habits or alter their behavior.
In some communities, including many parts
of DC, the nutrients recommended by
the National Cancer Institute and other
organizations may not be readily available as affordable staples in local food
markets. And heavily outweighing public messages about healthy eating is the
saturation advertising and pervasive marketing (especially to the young) of
heavily processed foods and beverages low in nutritional value and high in
fats, sugars, and calories—as well as tobacco companies’
continued subtle advertising to the young. Working parents, short on time, may
find it
difficult to cook fresh meals for their families, and instead rely on fast food
and processed foods. Finally, the
elimination of some physical education classes in many grades and schools has
reduced emphasis on physical activity.
GOAL: Reverse the trend toward
obesity and overweight by increasing physical
activity and the consumption of fruits and vegetables and by reducing caloric
intake among DC residents.
1) Reduce the prevalence rate of
obesity among DC adults to 15% by 2010.
2) Reduce the prevalence of overweight
adults to 40% by 2010.
3) Reduce the prevalence rate of
overweight and obese children to 5% by 2010.
4) Increase to 60% the prevalence rate
of adults who engage in regular, moderate
physical activity for at least 30
minutes a day at least five days a week by 2010.
5) Increase to 40% the prevalence rate
of high school students who engage in
moderate physical activity 30 minutes or
more, five or more days a week by 2010.
• By January 2008,
develop and maintain an intervention clearinghouse that encourages
collaboration among partners; provides resources to program planners and
resources to
the public about nutrition, physical activity, and reduced cancer risk; and
provides sample ordinances, organizational initiatives, and strategies.
• Develop a community-based
volunteer cadre to counsel families on health education and
preventive measures for cancer and other diseases.
• Develop culturally
appropriate materials and promote prevention activities through community
educational forums, the media, the DC government, employers and other vehicles.
• Include prevention
information in all DC forums that address cancer issues.
• Join or supplement the
efforts of other local organizations interested in controlling obesity, such as
the American Heart Association and American Diabetes Association.
• Through the Mayor’s
Council on Physical Fitness, implement school and work-based
programs for interventions designed to improve healthy eating habits and
physical activity, especially among children, teenagers, and young adults.
• Encourage employers to
adopt programs that promote physical activity, such as onsite
exercise facilities and subsidies for gym or athletic club memberships.
• Support Board of
Education efforts to provide healthy, well-balanced meals to students in grades
K-12, and to encourage good life-long eating behaviors.
• Decrease the
availability and marketing of foods and beverages of low nutritional value in
schools and increase the availability of nutritious food products.
• Through professional organizations,
conduct educational programs so that physicians can promote the benefits of
prevention practices to their patients.

Facts in brief
• When
states are ranked for mortality rates, DC ranks highest for deaths from
all smoking-related cancers—for both
men and women (see Table 1). The high
mortality rates for these cancers may
help explain DC’s high overall death rate
from cancer.
• Of the roughly 650 cases of smoking-related
cancers a year in the District, about
400 are lung cancer. Most lung cancers
(80 to 90% of cases) are attributable
to smoking. As many as 75% of oral cavity
cancers are probably attributable to
smoking. Cancers of the lung, larynx,
oral cavity and pharynx, esophagus,
stomach, pancreas, bladder, and urinary tract occur more often in smokers
than in nonsmokers.
• The lung cancer
mortality rate for Black males in DC is similar to the Black rate nationally,
but the rate for White males in DC is only 64% of the national rate for White
males. In fact, for both White men and women, DC has the lowest lung cancer
mortality rate of all states. This fact explains why the lung cancer ranking
for the combined races in DC is closer to the average for the
United States
.
However, the very high mortality for all other smoking-related cancers in DC
overwhelms the lower rate for the more frequent lung cancer and results in DC
leading the nation in mortality for all combined smoking-related cancer
sites.
• DC’s Black males carry
the heaviest burden of combined smoking-related cancers. The 5-year incidence
rates for these cancers is about 50% higher in DC’s Black males than in the
same race/gender group nationally. The rate in DC’s Black women is only
slightly higher than rates for Black women nationally. The incidence rates of
the other smoking-related cancers in White men and women in DC are slightly
lower than the national rates.
• In comparison with
national Surveillance, Epidemiology and End Results (SEER) data, the incidence
rates for smoking-related cancers in DC Black males show a greater excess than
do the mortality rates according to data from the North American Association of
Central Cancer Registries (NAACCR), suggesting that the high mortality ranking
for DC is due to the cancers’ more frequent occurrence rather than poorer
survival rates after onset of cancer. The same conclusion can be reached for
White males and females but not for Black women.
• The incidence rates
for these smoking-related cancers comparing Black and White males within DC
show even greater differences than comparisons with national rates. Rates for
DC Blacks are 2-2.6 times higher than for DC Whites. Black women living in DC
also have
incidence rates that are 1.8 times higher than those for White women living in
DC. The
disparity by race in the risk of these cancers for both sexes is greater in DC
than in the nation.
• The risk for various
cancer sites in DC Black males is 2 to 8 times higher than for other
groups by ages 55-64, according to NAACCR data.
• The higher incidence
of smoking-related cancers in DC’s Black population is not attributable to DC’s
urban characteristics. DC rates are higher than rates in
Atlanta
, a comparable East Coast city with a
large Black population and minimal heavy industry.
• Mortality rates for
the combined smoking-related cancers for Blacks in DC are among the highest in
the country, whereas the same rates for Whites are among the lowest—which means
there is a huge disparity in rates by race in DC.
• Since Black males in
DC are at higher risk than other racial/ethnic groups for smoking-
related cancers, the goal of any smoking control program in DC should be to
reduce the
proportionate number of Black smokers to a level similar to that for Whites.
Smoking-related cancers in DC
Inequality is the most striking feature of
incidence and mortality rates for smoking-related cancers in the District.
Mortality rates from lung cancer are close to the
U.S.
average
for all DC residents compared with
U.S.
residents generally. However,
for the combined smoking-related cancers occurring in the aerodigestive system
(lung, larynx, oral cavity, esophagus and stomach), as seen in table 1, DC
ranks first or second in the nation in mortality rates for both men and women. Mortality
rates can reflect not only differences in what causes the disease but also
differences in
access to health care and possibly differences in responses to treatment. The fact that the
differences in
incidence are much greater than the differences in mortality in comparing rates
for Blacks and Whites suggests that the major reason for the higher excess
mortality in DC in Blacks is the greater frequency of disease in this group.
The goal of a smoking-related program for cancer control in DC should aim at
reducing this racial disparity.
The incidence rates of lung cancer and other smoking cancers
by ward or geographic area and gender in DC show major differences (see Table
2). For example, lung cancer rates in males are higher in Wards 1, 4, 5, 6, 7,
and 8 than for males in Wards 2 and 3. Lung cancer and other smoking cancer
rates are not always highest in the same wards, however, nor do the highest
wards necessarily demonstrate the same excesses
for men and women. Ward 3 has the lowest rates for almost all cancers for both
men and women. No single ward has the highest rate for all of the cancers,
despite the fact that these cancers all have smoking as a unifying risk factor.
(All data represent an analysis for a five-year period to stabilize the rates
by ward).
Survival
Survival rates from smoking-related cancers are generally
very poor. The 5-year survival rates from these cancers (except for larynx and
oral cavity cancers) range from 9% to 22%. Even oral cavity and pharyngeal
cancers, with survival rates as high as 60%
in the White population, require extensive
surgery, which is often disfiguring, thereby limiting social interactions and
reducing
quality of life. The
U.S.
data
indicate that survival following these cancers is generally poorer for men than
it is for women and
poorer for Blacks than for Whites. Survival is particularly poor for Black
males. Although options for screening are limited for many of these cancers,
head and neck cancers, the commonest of smoking cancers other than lung,
are amenable to screening (see separate chapter on the
subject).
The health burden from smoking
The health burden from smoking is not
confined to cancer. Where there are high rates of smoking, excesses in
mortality and
hospitalizations for cardiovascular disease, stroke, and chronic obstructive
respiratory
disease are expected. The respiratory
problems in smokers will also result in lost work time and poor quality of
life, because
of restricted activity. In women, the burden of smoking is often seen in poor
reproductive performance, including infants born prematurely or small for their
gestational age.
The burden from smoking is also borne by individuals who live
or work with smokers
and are passively exposed to smoke. This environmental contamination increases
the risk of lung cancer, heart disease, and other conditions. Reducing smoking
rates brings about a fairly immediate reduction in the health and cost burden
from some major diseases, whereas the effect on cancer rates may be delayed for
10 to 20 years. Any program that reduces smoking rates will reduce health costs
from several diseases, many of which occur with high frequency and high cost.
Risk factors for lung cancer
Several kinds of
occupational and environmental exposure have been associated with the
risk of lung cancer, but the factor that explains 80 to 90% of cases is
cigarette smoking. The risk of lung cancer is reported to be 10 to 20
times higher in smokers than nonsmokers, depending on how long they smoked and
how many cigarettes a day they consumed. Black men have higher incidence and
mortality rates from lung cancer, are younger at age at
diagnosis, and have worse chances for
survival than White men.
While direct exposure to tobacco smoke is
the most important risk consideration, any
exposure to tobacco smoke carries a risk. Passive exposure to secondhand smoke
has been estimated to increase the risk of lung cancer by about 25%. The more
cigarettes smoked, the greater the risk to nonsmokers exposed to the smoke.
Exposure to environmental tobacco smoke (ETS) is suspected to increase women’s
risk of heart disease and children’s risk of respiratory conditions such as
asthma attacks, especially in children under the age of 10. In a population
with smokers, nonsmokers’ health may be damaged the same way indirectly as
smokers’ health is damaged directly. Reducing the number of smokers in DC will
reduce not only the direct effects of tobacco on smokers but also will reduce
exposure of non-smokers to environmental tobacco smoke.
Other factors that have been associated with a risk of lung
cancer are radon in homes, other environmental radiation, and several
industrial chemicals, such as coke oven gas and metals from chromium refining.
None of these factors should play a major role in lung cancer risk
in DC.
Risk factors for other smoking-
related cancers
For the other smoking-related cancers,
smoking represents an important risk factor
but not the only one. Tobacco is a major and independent risk factor for
cancers of the larynx, oral cavity and pharynx, stomach, and esophagus. For all
these cancers, British doctors have demonstrated a sevenfold increased risk for
smokers over nonsmokers; heavy smokers had 15 times the risk of nonsmokers.
Several studies have shown smokers to be at 3 to 13 times higher risk of oral
cavity and pharyngeal cancers than nonsmokers.
Current smoking levels in DC
Historically, Blacks as a race reportedly start smoking later
than Whites and smoke fewer cigarettes, but this pattern may be changing.
According to the Behavioral Risk Factor Surveillance System (BRFSS) (see Table
3), smoking rates in 2003 are higher for Blacks in DC and in the
United States
than for Whites. However, since DC has a population of African immigrants who
smoke, the increase in
smoking reported by Blacks may be attributed to the African immigrant and/or
African
American population.
The reported rate of smoking among
Hispanics in DC is higher than the
U.S.
rate
for Hispanics.
The rate for smokers in DC with low education levels is 43%
higher than the overall DC
smoking rate and 11% higher than the
U.S.
rate for smokers with low
education. The high rate for smokers with little education suggests that the DC
smoking rate may be associated with low-income residents, which could
explain some of the disparity in lung cancer rates by race.
Preventing smoking-related
cancers
Smoking cessation has been the main focus in reducing
tobacco-related cancers, but the ideal primary prevention strategy is to keep
people of all ages from starting to smoke in the first place—because tobacco is
one of the most addictive drugs. Of course, to stop smoking at any age will in
the long run reduce the risk of smoking-related cancers. The
benefits from smoking cessation not only
reduce cancer risks but also may be felt
more immediately and more dramatically in terms of reduced risks of
cardiovascular
disease and reproductive problems.
Secondary prevention through screening or early detection is
important only for oral cavity
cancers. For the other smoking-related
cancers, no practical screening programs
have been developed. .
Aims of a DC smoking program for
cancer control
Any anti-smoking program in DC should aim to do four things:
• Prevent the initiation
of smoking.
• Reduce the number of
current smokers
• Decrease exposures to
secondhand smoke
• Reduce the racial
disparity in smoking-
related cancers by providing effective
smoking-cessation programs for all races.
Each of these aims will demand programs with slightly
different emphasis but the programs should overlap as part of an integrated
community-based plan that includes all five objectives below. Each objective
must be
considered separately but the programs for
all five objectives should be integrated.
Funding for tobacco control in DC
To date, the
District of Columbia
has
spent none of the $57.4 million tobacco-generated
revenue it has received from the tobacco settlement payments and tobacco excise
taxes for tobacco control and prevention. The District opted to securitize part
of its settlement payments in exchange for a lump-sum payment to repay existing
long-term debt. The Centers for Disease Control and Prevention has set minimum
expected levels for states to spend on tobacco control and prevention. For DC,
the minimum expectation is $7.5 million annually. The District ranks worst of all states in the amount and percent of
tobacco settlement funds it has spent on tobacco control and smoking
prevention.
To DC’s credit, the
tobacco excise tax is $1.00
per pack.
California
,
Massachusetts
,
and Canada have proven that there is a
direct relationship between increasing the tobacco excise tax and reducing
tobacco use. Sadly, though, the revenue from the tax has not been appropriated
for programs to prevent or reduce tobacco use.
GOAL: Reduce mortality from
smoking-related cancers in the
District
of Columbia
.
1)
Reduce the level of smoking among high school students from 13% to 10% by
the year 2010.
• Initiate anti-smoking programs and smoking
cessation programs in all high schools. Use programs similar to current DC
programs and adapt programs used successfully elsewhere. Programs for smoking
cessation must be racially and culturally appropriate and should involve both schools and other points of
contact (such as youth centers, family planning clinics, pregnancy clinics, and
maternal and child health clinics that see youths under 20).
• Consider new approaches to reaching young
smokers, possibly using a “cluster” approach that engages youths’ parents and
peers.
• Consider an increase
in the cigarette excise tax in 2007.
2)
Reduce the level of smoking in current Black and Hispanic smokers and those
with low levels of education by 25% by
the year 2010.
• Establish a smoking cessation quit line for DC
youth and adults that will address the needs of a multilingual and culturally
diverse population. Include counseling and pharmacotherapy components.
• Target promotion of the cessation quit line to
specific racial, ethnic, and geographic
populations.
• Launch a targeted media blitz against smoking.
• Educate professionals
about their importance and effectiveness in persuading smokers
to stop.
3)
Reduce general exposure to secondhand smoke by creating a smoke-free
environment in all public places by the
year 2006.
• Advocate for
legislation that bans smoking in all public places.
4)
Reduce racial disparities in smoking prevalence.
• The minimum objective
for DC—a thread running through the previous three objectives—should be to
ensure that DC meets tobacco goals for Healthy People 2010 (Reduce
adult smoking to 18.5%) and meets CDC’s recommended level of funding for
anti-smoking activities ($7.5 million annually).

Facts in brief
• Oral
cavity and pharynx cancers occur 1.7 times more frequently in Black males in DC
than in Black males countrywide. (Local and national incidence rates in White
males and in women of both races are similar.) Black males in the District are
2.4 times more likely than White males to be diagnosed with these cancers.
• Black males with oral
cancers have only half the chance White males have of surviving for 5 years.
The poorer survival rates of Black males are partly due to their cancers being diagnosed
at a more advanced stage than those of White males.
• Incidence rates of
cancer at each site in the oral cavity are low but the combined rates represent
about 40% of all other smoking-related cancers, except lung cancer, in Black
males. The higher rates of cancer in Black males appear to be concentrated in
lesions of the tongue, the floor of the mouth, the oropharynx, and the
hypopharynx. Lesions at many of these sites would be visible on direct
examination of the oral cavity.
• The age-specific rates
of oral cavity cancers are higher in Black males beginning at ages 35–44, and
the rates for Black males increase more rapidly than for other race and gender
groups. The rates peak at ages 55–64, when oral cavity cancers are 2.5 times
more likely
for Black males in DC than for White. For Black males in DC, the rate of oral
cavity cancer
declines after age 64, differing from other smoking-related cancers (including
lung and
stomach cancers), which generally show a gradual increase in risk extending
past the age
of 75. This may suggest other risk factors for these cancers besides smoking or
other
population differences.
• Ward 3 has the lowest
rate for oral cavity cancers in males. The range of rates by ward differs
4.6-fold. Some of the variation is due to differences in racial distribution by
ward.
• Patients with oral
cavity cancers have a better survival rate than patients with smoking-related
cancers at other sites, such as the lung, esophagus, and stomach. However, the
treatment
for this cancer may disfigure the patient, leading to a diminished quality of
life.
Cancers of the head and neck, including
tumors arising in the oral cavity and pharynx, are associated with smoking.
Risk factors
Smokers have a 3- to 13-fold higher risk of oral cavity and
pharynx cancers than nonsmokers.
Other factors, such as the use of smokeless tobacco products,
also play a role in oral cavity cancers. Data are not available on adult use of
smokeless tobacco in DC. According to national data for 2003, 5% of high school
students in DC use smokeless tobacco.
Risks for oral cavity cancers double in heavy drinkers,
compared with those who abstain from alcohol or are light drinkers. Moreover,
studies suggest that combined exposures to smoking and heavy drinking in the
population may increase the risk of oral cancer to higher levels than the added
risks from each
substance alone. Exposure to both heavy drinking and smoking increases the risk
almost 80-fold while the risk from heavy smoking alone may be only 17-fold and
the risk from heavy drinking alone only two-fold. Because the two exposures
often occur together, most of the cancers will be related to both risks.
Differences in diet are thought to influence the risk of oral
cancers. In fact, Chinese people from certain areas of
China
who eat
salted fish have an especially high risk of nasopharyngeal
cancers. Exposure to selected chemicals, such as formaldehyde and methyl ethyl
ether, may increase the risk of selected sites of pharynx, nasopharyngeal and hypopharynx cancers.
Preventing oral cancers
Because oral cavity cancers are related both to cigarette
smoking and smokeless tobacco products, campaigns encouraging people never to
use the products and programs
helping people stop using them could both
be effective.
Oral cancer patients have a 15% risk of
developing a second cancer of the head and neck or in the lungs—a much higher
risk of second cancers than for other cancer sites. Many deaths from
head and neck cancers are the result of second cancers. Many of these second
lesions occur in the oral cavity or pharynx but may also occur in the larynx,
lung, or esophagus. The risk of developing some second cancers might be
prevented or the
effects modified by changing patients’
smoking or drinking habits and by early
detection through screening.
Two factors—the high probability of second cancers and a risk
for combined exposures that is greater than additive—strengthen the impact of
reducing smoking. Where there is
a synergistic effect between two common exposures and especially if the
behaviors
frequently occur together, reducing the
exposure to either factor will greatly reduce
the risk of the cancer. Early detection of a
second cancer, or even of premalignant
lesions, may improve the patient’s chances
for survival. Secondary prevention programs could be successful in reducing
both
advanced oral cancer lesions and deaths. They would focus on detection of both
precancerous lesions and early-stage disease. Except for pharynx cancers,
common sites should be visible on clinical examination.
Early detection is particularly important in
oral cancer prevention because survival is significantly improved if the
lesions are small at diagnosis and the extent of surgery may be less. Since
surgery for advanced head and neck cancers is extremely deforming, the
patient’s quality of life could be improved
with less radical surgery. Although cancer organizations may not suggest
screening
programs for all head and neck cancers
because the cancer is relatively rare, it is
important to add oral cavity screening to
routine clinical examinations, especially by both dental and medical
practitioners, and to focus screening programs on high-risk groups.
Secondary prevention would include a
program to teach both physicians and dentists to look for early lesions in the
oral cavity and to provide appropriate care for leukoplakia and erythroplakia.
The professionals could train their patients to perform self-examination for
these lesions. The white or reddish raised plaques found on oral mucosa are
often a precancerous condition.
Dentists may perform oral cavity screening routinely but
older populations often do not use routine dental services so it is important
to train physicians to perform the screening—especially for the elderly, who often
see medical doctors for chronic health problems. Physicians may also need to be
reminded of the high risk of second primaries of the oral cavity or pharynx in
patients with an original primary cancer of the aerodigestive tract.
Freestanding oral cancer screening programs are often underused. Primary
prevention programs for smoking cessation can be added to these screening
programs to enhance their effectiveness. Screening programs might be targeted
at high-risk populations such as men in jails and halfway houses and other
sites with many high-risk occupants who have had little contact with medical or
dental services before living in such group facilities.
Signs and symptoms of head and
neck cancer
The most common symptoms of head and neck cancer are listed
below. Usually, only one sign or symptom is present.
• An ulcer or sore area
in the head or neck that does not heal within a few weeks
• Difficulty in
swallowing, or pain when
chewing or swallowing
• Trouble with breathing
or speaking, such
as persistent noisy breathing, slurred speech or a hoarse voice
• A swelling or lump in
the mouth or neck
• Pain in the face or
upper jaw.
GOAL 1: Reduce the mortality rate
in DC from cancers of the head and neck by 10%.
GOAL 2: Reduce the incidence of
invasive cancers of the head and neck in
DC
by 10%.
Increase to 50% the proportion of head
and neck cancers detected at the local stage for both men and women by 2010.
• Educate dentists, physicians, and other health
care providers about screening all patients, especially those who smoke, for
early signs of head and neck cancer.

Facts in brief
• Among women,
breast cancer is the second leading cause of cancer-related deaths nationally,
after lung cancer. Nationally, it is the most commonly diagnosed non-skin
cancer among women, accounting for nearly one-third of all cancers diagnosed.
Over her lifetime, a woman has a one-in-seven chance of developing breast
cancer.
• Almost 80% of breast
cancers are diagnosed in women aged 50 and older. More than half of breast
cancers are diagnosed in women aged 65 and older. Women 65 and older have a significantly higher
mortality rate (148.9) than women 64 and younger (19.8).
• Roughly 80% of women
diagnosed with breast cancer have no known risk factors.
• Nationally, White
women have the highest incidence rate (140.8. cases per 100,000 women),
followed by Black women (121.7), Asian/Pacific Islander women (97.2), and
Hispanic women (89.8).
• However, Black women
have the highest mortality rate nationally (35.9 deaths per 100,000 women),
followed by White women (27.2), Hispanic women (17.9), and Asian/Pacific
Islander women (12.5).
• Between 1992 and 2000
the incidence rate for Black women remained the same. However, Black women were
more likely than White women to be diagnosed with large tumors (larger than
5.0cm).
• White women have a
higher incidence of breast cancer after age 42; Black women have a slightly
higher incidence rate before age 42.
• Incidence rates have
remained relatively stable, increasing only 0.4% from 1987 to 2000.
Mortality rates declined 2.6% annually from 1992 to 2000—but the decline was
twice as great for White women as for Black women.
• About 10% of women who
are carriers of the BRCA1 or BRCA2 gene develop breast cancer.
• The District has the
highest breast cancer mortality rate in the country (at 37.3 per 100,000
women).
• In 2005 an estimated
520 women in the District will be diagnosed with breast cancer and
100 will die of the disease.
• The incidence rate in
DC (143.3), the fifth highest among all states, is considerably higher
than the national average (132.2).
• Men can get breast
cancer, but male breast cancer is rare (1,300 cases per year).
Breast cancer is the most
frequently diagnosed cancer among District women and the second most frequently
diagnosed cancer among all District residents. The incidence rate is highest in
Ward 2 (224.3 per 100,000 women),
followed by Ward 3 (173.0), as Table 1 shows.
The mortality rate from breast cancer is the third highest
cancer mortality rate in the District. Ward 2 has the highest breast cancer
mortality rate (48.8), followed by Ward 5 (41.7), as Table 2 shows.
Research has documented treatment
differences between Black and White women. Many researchers attribute the
delayed
diagnosis of breast cancer in many Black women to a lack of health insurance or
limited access to mammography, although there is some indication that cultural
beliefs about health care and socioeconomic factors, such as income and
education, may explain some of this disparity. But Black women, especially
those
younger than 45, also develop more aggressive tumors than
White women. Those aggressive tumors are difficult to treat and often present
at a late stage. Mutations in the p53 tumor suppressor gene, which are
associated with poorer outcomes, are more likely to occur in Black women and
might make chemotherapy treatment less effective.
Risk factors
Modifiable risks
Studies have shown the risk of breast
cancer to increase slightly with increased alcohol consumption.
Many cohort studies have
found that obesity increases the risk of postmenopausal women developing breast
cancer.
Studies suggest that
reproductive hormones promote the growth
of some cancers. Recent use of hormone (estrogen) replacement therapy (HRT) has
been shown to increase the risk of breast
cancer (the longer the period of HRT,
the greater the risk).
Nonmodifiable risks
The risk of
developing breast cancer
increases with age, for both men and women. Most breast cancers occur in women
over the age of 50; the risk is especially high for women over the age of 60.
Only 10% of
women who develop breast cancer are genetically
predisposed to developing the disease.
Mutations in two genes (BRCA1 and BRCA 2) account for nearly half of these
inherited forms of breast cancer. In addition, women who have two or more
first-degree relatives (mother, sister, aunt) with breast cancer diagnosed
at an early age are at increased risk for
developing the disease.
Women with an early
onset of menstruation (before age 12) are
at higher risk of developing breast cancer. In general, breast cancer risk
declines 10% to 20% for each year menarche was delayed. Epidemiological studies
have consistently demonstrated that late onset of menopause (age 55 and over)
is associated with greater risk of breast cancer.
Women who experience more
pregnancies are at decreased risk, and women who bore their first child when
they were 20 years old or younger have about half the risk of women who
completed their first full-term pregnancy at age 30 and over. Women who never
have children or have their first child after age 30 are at slightly increased
risk.
When cultural
comparisons are made, lesbian women
appear to be at higher risk of breast (and
cervical) cancer because of delayed
screenings and higher rates of alcohol consumption, tobacco use, obesity, and
never having given birth to a viable infant.
Ways to reduce the
incidence of breast cancer
Certain actions may lower (but not eliminate) women’s risk of
developing breast cancer. Lifestyle changes that may help reduce women’s risk
of developing breast
cancer include limiting alcohol consumption,
eating a low-fat diet, breastfeeding their
infants, and increasing physical activity. In the
District of Columbia
:
• Nearly 30% of women 18
and older report engaging in no physical activity.
• More than half of
adult women in the District, and 68% of Black women, are considered overweight
(with a body mass index greater than 25.0). Rates of obesity continue to
increase.
• DC residents with only
a high school
education have overweight rates over 70%.
Research has shown that tamoxifen and other agents can reduce
the risk of breast cancer in women who are at high risk for developing the
disease, and the risk of recurrence in women who have already had breast
cancer. These agents do have side effects.
Prophylactic mastectomy is an option
available to women with moderate to high risk of developing breast cancer in
their lifetime.
The procedure can reduce the risk by 90% in women who are at
moderate to high risk. However, this is a drastic procedure and should be considered
very carefully. It is often regarded as an important option for women who carry
the BRCA1 or BRCA2 genes or who are at very high risk for breast cancer
because of a strong family history of the
disease.
Ways to reduce deaths from
breast cancer
There has been
a modest decline in deaths from breast cancer, which has been attributed to
successful screening programs and improvements in treatment. Mammography, an
X-ray of the breast, detects about 90% of breast cancers in women without
symptoms. Often these cancers are too small for health care providers
to feel during clinical breast examination. Mammography screening may identify
women who have cancer or precancerous lesions in the breast that require
further evaluation, including a biopsy. Results from post-mammography biopsies
are non-cancerous in 70
to 80% of women. Mammography testing is more accurate in
postmenopausal than in premenopausal women. The breast tissue in younger women
is denser than that in post-menopausal women, making it more difficult for
mammography to detect breast cancer.
Women diagnosed with breast cancer at an early stage, when
the tumor is confined to the breast (localized), have a 97% chance of surviving
5 years; when the cancer has spread to the region around the breast, 78%; and
when the cancer has spread to other organs, 23%. Table 3 shows data on stage of
cancer at diagnosis in District wards.
Although some recent studies have cast doubt on the value of
mammography screenings, both the National Cancer Institute and the American
Cancer Society firmly support the value of mammography as a means of
detecting breast cancer at an early stage. The American Cancer Society
recommends that:
• Women get yearly
mammograms starting
at age 40.
• Clinical breast exam
(CBE) be part of a
periodic health exam about every three years for women in their twenties and
thirties, and every year for women 40 and older.
• Women know how their
breasts normally
feel and report any breast change promptly to their health care provider.
• Women at increased
risk (through family
history, genetic tendency, or past breast
cancer) talk with their doctors about the benefits and limitations of starting
mammography screening earlier, having
additional tests (such as breast ultrasound and MRI), or having more frequent
exams.
According to the Behavioral Risk Factor
Surveillance System (BRFSS), although
proportionately more women in DC are getting
recommended mammograms than do so
nationally, 30% of women in the District are
still not being screened regularly for breast cancer (see table 4). Only 69% of
women in the District 65 years old and older reported having had a mammogram in
the past year, although the incidence of breast cancer increases the most among
women in their sixties.
More Black women (72%) are receiving
mammograms than White women (62%) in DC, but only 64% of women with less than
a high school education are receiving
mammograms.
In 2004, the Delmarva Foundation, a quality improvement
organization, reported that only 51% of Black women on Medicare (age 65+ and/or
disabled) are being screened for breast cancer, compared with 61% nationwide.
If a palpable mass is present or a
mammogram reveals a suspicious lesion, a
biopsy is needed to determine the nature of the lesion, or mass. Three types of
biopsy procedure are available: fine needle aspiration, core biopsy, or
excisional biopsy. Each has advantages and disadvantages. The type of biopsy
required often depends on the mass’s location, size, and visibility on the
mammogram.
Breast cancer is commonly treated
by a combination of surgery, radiation therapy, chemotherapy, and hormone
therapy. Surgery is still the first line of treatment, but researchers have
found that less extensive, more conservative surgery is just as effective as
radical surgery. Now surgeons may remove
only the tumor or only a small part of the breast, especially if the cancer is
small. One reason for regular mammograms is to find the small tumors so that
extensive surgery is not needed. For large tumors, a simple or more extensive
mastectomy may be necessary, but reconstruction of the breast is often
possible. In some cases, radiation or hormonal therapy or chemotherapy may be
required in addition to surgery. The additional treatment is designed to remove
any residual tumor that may have not been visible at surgery.
Selection of therapy is influenced by age, menopausal status,
stage of disease, the
tumor’s histologic and nuclear grade, and status
in terms of estrogen and progesterone, among other factors.
The earlier the breast cancer is diagnosed, the more treatment options women
have.
Barriers to reducing the breast
cancer burden
Some women avoid mammograms out of a belief that
screening is unnecessary if the woman is asymptomatic or has no family
history of cancer. Others fear a diagnosis of cancer. One study found that
Blacks knew less about cancer and were more fatalistic about it than Whites.
Age, poverty, and
isolation make it difficult for many women in the District to get either
primary care or cancer care. In a city with a high cost of living, 36% of
residents are at 200% of the federal poverty level or below. For 30% to 40% of
minorities, cost is the reason women report failing to follow up on their
physicians’ recommendations. Women also have trouble getting time off from work
and finding adequate transportation and child care. English is not the primary
language for about 17% of DC residents, and access to language interpreters is
limited. Poor literacy, including poor health literacy, makes it difficult for
many patients to understand and follow instructions from the doctor or the pharmacy.
Minority
and immigrant residents report they do not sense an understanding or respect
from physicians who do not share their racial and ethnic heritage.
The waiting time for a
mammogram in DC is now five weeks. For women who have trouble getting time off
from work, finding help with child care, and making their way on public
transportation to screening
services and clinical breast exams, having to wait
a long time to be seen is discouraging.
They often lose their motivation and fail to show up for appointments.
There are too few mammography facilities, especially in areas
that serve the poor.
D.C. General
Hospital
closed all inpatient
services in spring 2001 and some outpatient services, including breast cancer
screening.
Hadley
Hospital
and
Columbia
Hospital
for Women, primary providers of mammography and
other breast health services, also went out
of business.
There are insufficient public screening and treatment
resources for the medically
underserved through Project WISH, the District’s Breast and Cervical Cancer
Early Detection Program.
It is unknown what percentage of women eligible for Project
WISH in DC are served. Nationwide Breast and Cervical Early
Detection Programs serve only 10% to
20% of the eligible population. The District government does not supplement
federal funding, so Project WISH must designate
most of its funds to serving women aged 50 to 64. There are few other resources
in the District to screen women between the ages
of 40 and 49.
In DC,
community health centers have difficulty
finding specialists who will take cases of
medically underserved women who need follow-up and/or treatment after a
suspicious mammogram.
instructions from the health care provider and following
through on the instructions) can be overwhelming to a person. Especially if a
woman faces any of the additional barriers mentioned above, she may not pursue
the screening or medical appointment.
GOAL: Reduce mortality rates from
breast cancer in the District by 10%, especially among Black women.
1)
Reduce the incidence of invasive disease in DC by 10% by 2010.
2)
Increase the number of women aged 50 through 64 who are screened annually
by 10% by 2010.
3) Reduce the proportion of unstaged
cases to less than 5% by 2010.
• Partner with community organizations and local
breast cancer organizations to bring tailored messages about breast cancer
screening to all medically underserved Black women and to women 50 years old
and older. Encourage such groups to enlist the help of influential public
figures from whom such messages might be more persuasive. Tailored messages
should
address myths, fears, and negative attitudes about breast cancer and screening.
• Partner with local Centers for Medicare and
Medicaid (CMS), AARP, senior service
organizations, and the Department of Motor Vehicles to educate Medicare and
Medicaid
beneficiaries about the benefits and coverage for breast cancer screening.
• Make information about
resources for breast cancer screening, treatment, and support readily available
to women.
• Advocate for sufficient city funding for Project
WISH to supplement federal funding, so that
the program can reach at least 50% of the women eligible for the program.
• Subcontract additional components of Project
WISH if management and budgeting for the program are inadequate or unstable.
• Develop a system that coordinates and connects
community health centers with hospitals to ensure continuity of care regardless
of patients’ insurance or payor status.
• Implement a patient navigation system in DC to
help women connect with appropriate
diagnostic services, treatment facilities, medical appointments, second
opinions, and
follow-up examinations.
• Expand the mobile
mammography screening program, especially for Black women. Such a program could
also screen for hypertension, cholesterol, and other diseases.
• Ensure that all appropriate health
care providers know about breast cancer screening
guidelines, local resources for screening and treatment of medically
underserved women,
and community resources that support screening, treatment, and referral.
• Ensure that all appropriate health
care providers are trained to provide clinical breast
examinations for women at the appropriate age.
• Make a family history of breast
cancer a required part of every woman’s medical record.
• Encourage physicians to set up
effective reminder systems for annual screening of female patients.

Facts in brief:
• Gynecologic cancers account for 6% of cancers
diagnosed in the
District of
Columbia
each year. Close to 200 cases a year are diagnosed, including about
50 cases of invasive cervical cancers,
more than 40 of ovarian cancer, 70 to 90
of endometrial (uterine) cancer, and
an unknown number of pre-invasive cervical
cancers.
• Death from one
gynecologic cancer—cervical cancer—is avoidable. Since the
introduction of Papanicolaou (Pap)
smear screening programs in this country in
the 1950s, cervical cancer mortality
rates have declined by about 75%. Despite
high rates of disease, cervical cancer
mortality has declined in DC as well.
• DC has the highest
rate of cervical cancer in the
United
States
, and the proportion of cervical
cancer cases diagnosed in advanced and unknown stages is greater in DC than in
the rest of the country (see Figure 1). Nearly all cases (92%) of invasive
cervical cancer are diagnosed among minority women. Only Black women in DC have
higher than
U.S.
average death rates from cervical cancer. Yet invasive cervical cancer is a
preventable disease. The main reason women are diagnosed after cervical cancer
has spread and the main reason they die—is that they have not received a Pap
smear. Evidence shows that women are most likely to get a Pap smear if a doctor
recommends it.
• Endometrial (uterine)
cancer is often a curable disease. In 95% of cases there is vaginal bleeding.
Women should be alerted to recognize bleeding after menopause as an early
warning sign that could lead to earlier diagnosis and the greater likelihood of
a cure.
A single intervention could reduce deaths
from cervical cancer. Unfortunately, fewer
interventions exist for the other gynecologic cancers, although new screening
tests may be on the horizon. In this chapter we provide information about, and
suggestions for controlling, cervical cancer, endometrial
(uterine) cancer, and ovarian cancer in the
District of Columbia
.
CERVICAL CANCER
In the diagnosis and treatment of cervical cancer, regular
use of Pap smear screening is critical because precancerous changes can be
detected and readily treated. Pap smear
screening rates have increased dramatically in the past two decades; well over
80% of women surveyed nationally reported having had a recent Pap test.
The past 3 years and 94% reporting they ever had a Pap smear.
Despite these high rates, there has been a worrisome decline in the proportion
of women reporting a recent Pap smear (see Figure 2). There is some indication that
this trend reflects an influx of Latinas, many of whom are emigrating from
countries with very high rates of cervical cancer and poor access to screening.
Almost all women with cervical cancer are infected with human
papillomavirus (HPV), which is the main cause of this cancer. (Note, however,
that although infection with HPV is apparently necessary for cervical cancer to
develop, most women infected with HPV clear the infection spontaneously and do
not
develop cervical cancer.) Retrospective
reviews of new cases of cervical cancer, or
follow-back studies, consistently report that the majority (45% to 65%) of new
cases occur in women who have never been screened or among those whose last
test was three or more years before their diagnosis.
Among cases with recent screening, up to one-third of
cases have been interpreted as failure to detect existing
precancerous or cancerous lesions, and between 4% and 30% of cases failed to
receive timely, or any,
diagnostic evaluation.
Risk factors for cervical cancer
Studies show that several factors increase the risk of
cervical cancer. Risky behaviors exert their influence through their effects on
the risk of acquiring or maintaining specific strains of infection with human
papillomavirus (HPV). Women who are sexually active at an early age, or have
multiple sexual partners, are at greater risk of infection. Women who acquire
HPV are at greater risk of having that infection
persist to cause cancer if they are older, smoke, are pregnant, are infected
with HIV or are otherwise immune suppressed, have severely limited diets (poor
in folic acid, vitamin
C, and other micronutrients), or use oral contraceptive pills. Women who are
poor and have no health insurance or regular source of health care are at
greater risk of dying from advanced cervical cancer because, in that population
group, rates of screening, follow-
up on abnormal tests, and definitive cancer treatment are much lower. Women who
undergo a complete hysterectomy for conditions other than cancer are no longer
at risk of developing abnormal cervical tissue because all cervical tissue has
been removed.
fourth leading cause of death from cancer in Latinas in the
United States
.
According to SEER 2000 data, Latinas have the highest rates of cervical cancer
rates of all
U.S.
population groups.
Screening for cervical cancer
Screening for cervical cancer is recommended starting within
the first three to five years after the onset of sexual activity or by age 21.
After two or three negative annual Pap smears, screening is recommended every
two or three years. The American Cancer Society and
the
American
College
of Obstetricians and
Gynecologists recommend the FDA-approved HPV DNA test as a reasonable approach
to screening women 30 or older, as an alternative to examination alone. If a
woman has had more than five to seven normal Pap smears, including a normal Pap
smear within the past three years, screening can probably cease after age 65 or
70. Screening is also unnecessary for women who have had a hysterectomy for
noncancerous conditions or for women with medical conditions limiting life
expectancy to less than five years.
The most important reason that women
present with cervical cancer that has already spread or die from this disease
is failure to obtain a regular Pap smear. Roughly half of the
cervical cancers detected nationally are in women who have never been screened
and 10% are in women who haven’t been screened within the last five years. For
Pap smear screening to lead to early detection of precursors of cervical cancer
or invasive
disease, women must receive regular Pap smear screening, the quality of the
smears and their interpretation must be adequate, and when findings are
abnormal, follow-up and resolution must be prompt.
Nationally, the main reasons women don’t
get Pap smears include the following: Their
doctor fails to recommend it; they don’t have a regular health care provider,
live in an area with few primary care providers, or haven’t had a recent visit;
they don’t know where screenings are available or why screening is important;
they fear a cancer diagnosis or believe cancer cannot be cured; they want to
avoid the
inconvenience, discomfort, or embarrassment of the Pap smear; or they don’t
have time.
If they don’t have health insurance, cost is probably also a factor. And
cultural beliefs held by new immigrants or other minority groups may also
affect whether they seek screening. Similar problems with knowledge, attitudes,
and beliefs have been reported as barriers
to follow-up on abnormal screening tests or symptoms of cervical cancer.
The risk of dying from cervical cancer is
greater in the District’s medically underserved
communities, including southeast DC. Where there are fewer primary and cancer
care physicians there will be less patient education about risk factors, fewer
recommendations for screening, and less access to treatment. The most common
reason for failure to obtain a Pap smear is the health care provider’s failure
to recommend it.
Variations in sensitivity of Pap tests
Recent analyses suggest that Pap smears
in general practice vary widely in ability to detect changes in tissue.
Sensitivity may vary because of poor exfoliation of cells from the cervix,
inadequate sampling by the provider, and/or inaccurate laboratory
interpretation. Physicians also vary in their understanding of what makes a
smear unsatisfactory. With so much variability in test performance, some women
could be classified either false positive or false negative. There appears to
be no data summarizing screening quality in the DC area. Adding HPV testing
improves detection of true disease.
Follow-up after screening
Black women self-reported comparable or higher rates of Pap
smear use than Whites starting in the 1980s, but rates of incomplete diagnostic
follow-up and initial
diagnosis at the stage of invasive and
late-stage disease have been consistently higher among Black, Latinas, and
other
minority women. Problems with language,
acculturation, and access, as well as fewer years spent in the
United States
account for low screening rates and late diagnosis among minority immigrant
women.
Treatment for cervical cancer
Women diagnosed before
cervical cancer spreads have a dramatically better chance of survival. Two
other factors can influence stage-specific survival: the histological (cell)
type of cancer and the treatment prescribed. In general, there are two main
types of cervical cancer: squamous cell and glandular (adenocarcinoma). In the
few studies conducted, there appears to be no difference in histological type
in cancers in the DC (compared with
the
United
States
) that would lead to lower survival
rates in DC. But studies show that about 10% of all women diagnosed with
invasive cervical cancer receive no cancer-directed therapy or receive
inappropriate care. Minority women, older women, and women with distant or
unstaged disease are less likely to receive
cancer treatment. We found no studies of
cervical cancer treatment patterns in the
District.
Reaching women and preventing deaths
Invasive cervical cancer is a preventable
disease. Even the highest cervical cancer
rates in the country translate into relatively few women affected (compared
with other cancers), but all cases of invasive cervical cancer—especially those
arising from lack of screening or adequate follow-up—signal the public health
system’s failure to detect and treat this disease at its early, pre-invasive
stage. All cases of invasive cervical cancer should therefore trigger a
careful review of missed opportunities for
controlling the disease.
quality, and treatment are largely unmeasured in the
District, it is difficult to select a single “best” cancer control strategy.
Interventions that have proven effective elsewhere include mailed or telephone
reminders to get a Pap smear (which increased Pap smear use by up to 18.8%),
using a culturally appropriate lay health worker (which increased use by
18.0%), and offering same-day screening using a nurse-practitioner (which
increased screening by 32.7%). Various interventions should be tested and
evaluated for effectiveness with
different District populations.
Newer interventions in development may have future
applications in DC. For instance, vaccines to prevent infection in women with
HPV 16 and 18 are expected to become available in the near future. Immunization
would need to occur before the onset of sexual activity. Data on the efficacy
of HPV vaccines in males are not yet available. The first clinical trials have
shown 100% effectiveness, so this technology is promising.
ENDOMETRIAL
(UTERINE) CANCER
Endometrial cancer, which develops from the endometrium, the
inner lining of the uterus, is the fourth most common cancer in women, after
lung, breast, and colon cancer. In 2005 about 40,000 women nationwide will be
diagnosed with endometrial cancer; about 7,300 are expected to die of the
disease. About 70% of all cases of endometrial cancer occurs in women aged 45
to 74;
only 8% occur in younger women. The chance of any woman being diagnosed with
endometrial cancer is about 1 in 40, according to the National Cancer
Institute.
After increasing from 1988 to 1998, incidence rates of
endometrial cancer leveled off through 2001. The 5-year relative survival rate
is 85%, and when this cancer is diagnosed at an early stage—as is the case for
most
women—the 5-year survival rate increases to 96%.
Although this cancer is 40% more common
in White women, Black women are nearly twice as likely to die from it. Survival
rates for Whites exceed those for Blacks by at least 10 percentage points at
every stage
of diagnosis.
Burden of endometrial cancer in
Washington
,
DC
In 2002, 84 women were diagnosed with
endometrial cancer, and 31 died of the
disease, as reported in the latest information available from the DC Cancer
Registry.
Endometrial cancer mortality rates in DC increased slightly
from 1978-2002 but have remained stable in the period 1998-2002. Mortality
rates in the District for Black women are higher than those for White women,
and higher than those for Black women
nationwide.
Risk factors for endometrial cancer
According to a recent publication for
physicians from the
American
College
of
Obstetricians and Gynecologists (ACOG) and the Society of Gynecologic
Oncologists, the most common cause of endometrial cancer is an excess of
estrogen, a female hormone, often found in women who take estrogen
therapy alone after menopause. However, women who take combination birth
control pills (estrogen plus progestin) appear to have
a lower risk. Other risk factors include
• Not ovulating
regularly and often missing menstrual periods
• Beginning menstruation
before age 12
• A history of
infertility or never having
given birth
• Experiencing menopause
late in life
• Use of tamoxifen, an
anti-estrogen drug used to treat women with breast cancer
• Obesity and/or
diabetes
• A high-fat diet
• Family history,
especially for women with the inherited tendency to develop a type of colon
cancer called hereditary nonpolyposis colon cancer (HNPCC)
• Endometrial
hyperplasia (abnormal
thickening of the endometrium)
• Breast or ovarian
cancer
• Prior pelvic radiation
therapy.
It’s important to understand that only a small percentage of
women who have only one of these risk factors will develop endometrial cancer.
Interventions to decrease the
burden of endometrial cancer
Most cases of endometrial cancer
cannot be prevented. However, these steps can help lower risk:
• Use of oral
contraceptives. Taking these
for a long time appears to offer protection
for at least 10 years after a woman stops taking them.
• Controlling obesity
and diabetes
• Eating a diet high in
fruits, vegetables and whole grains
• Regular exercise.
At present there is no early detection test or
examination recommended for women without symptoms who are at average risk for this
disease. The American Cancer Society recommends that at the time of menopause,
women should be made aware about the signs and symptoms of this cancer,
especially the importance of seeking immediate treatment for any vaginal
bleeding. About 90% of women with endometrial
cancer develop vaginal
bleeding or discharge that generally leads to early diagnosis. The Pap test for
cervical cancer does not detect gynecologic cancers other than cervical cancer.
Treatment for endometrial cancer depends
on the type and stage of the cancer
when it is diagnosed and each woman’s overall health. It is important that
women with this cancer have their cancers thoroughly and systematically staged
to help determine the best course of treatment. Surgery is the most common
treatment for endometrial cancer, and in some cases radiation treatment may be
recommended. Chemotherapy may sometimes be used, and hormone therapy is also an
option for some forms of endometrial cancer.
After treatment for endometrial
cancer is complete, monitoring for recurrence should include pelvic
examinations every three to four months for two or three years, and
then twice a year thereafter. About 75% of
recurrences are found within the first three years of follow-up; thereafter,
recurrence is
less likely.
Barriers to care for endometrial cancer
Barriers include:
• The absence of a
screening test
• Unawareness of the fact that vaginal bleeding or discharge is an early and important
warning sign for this cancer—thereby
delaying diagnosis and treatment
• Limited access to
specialists, which may mean that initial surgery for this cancer may not
produce the careful staging of the
disease needed to determine optimal
treatment
• Delays in treatment,
inadequate monitoring of the disease during and after treatment, and inadequate
support for side effects from treatment because patients are uninsured or
underinsured (a recurrent theme).
OVARIAN CANCER
Ovarian cancer is the deadliest of gynecologic cancers,
accounting for more deaths than any other cancer of the female reproductive
system. This cancer, for which there is presently no screening test for the
general population, is the fifth most commonly diagnosed cancer among women,
ranking second among gynecologic cancers.
Ovarian cancer represents about 3% of all cancers diagnosed in women.
Nationally about 22,220 women are expected to contract the disease in 2005, and
16,210 women will die from it.
During 1995-2001, the incidence of ovarian cancer declined at
a rate of 0.8% a year, with rates declining fastest in women 65 or older. The
incidence of ovarian cancer is 18.1 for Whites (per 100,000 women, age-adjusted
to the 2000
U.S.
population standard) and 12.0 for Blacks. The mortality rate for Whites is 9.3;
for Blacks, 7.6.
In 1995-2000, about 78% of women with ovarian cancer survived
one year after diagnosis and, according to the American Cancer Society, the
overall 5-year survival rate is 44%. For women diagnosed and treated
before the cancer has spread outside the ovary, the 5-year
survival rate is 90 to 95%. But only 21% of ovarian cancers are found at this
early, localized stage.
Burden of ovarian cancer in
Washington
,
DC
In 2002, the latest data available from the DC Cancer
Registry reported that 41 women in the District developed ovarian cancer (see
Table 1), and 32 died of the disease.
The disease has a very high rate of recurrence, especially
for the great majority of women who are diagnosed with cancer that has spread
beyond the ovary. Women in recurrence often undergo years of treatment before a
majority succumb to the disease.
Statistics for
1997-2001 show that 58% of Black women diagnosed with ovarian cancer in DC have
advanced disease (regional or distant metastases), compared with 45% of White
women. Early-stage diagnosis is a strong predictor of treatment success for all
women with ovarian cancer.
It is worth noting
is that in the District, 24% of Black women and 28% of White women are reported
as having “unknown” staging. This suggests either pervasive reporting problems
or a relatively high percentage of surgery on ovarian cancer patients that may
not be performed by gynecologic oncologists, the physicians who specialize in
treating women with gynecologic cancers.
Risk factors for ovarian cancer
The risk of ovarian cancer increases with
age, especially at or after menopause. About 50% of all ovarian cancers are
found in women over 63.
Women with
a family history of ovarian cancer have a
higher risk of developing it. Women with a personal or family history of breast
and/or colorectal cancers are also at increased risk. Risk may be inherited
from either side of the family. However, only about 10% of ovarian cancers
result from an inherited tendency to develop the disease. Mutations of the BRCA
1 and BRCA2 genes produce a very high risk of ovarian cancer. Also, hereditary
nonpolyposis colon cancer (HNPCC), a syndrome caused by gene mutations, puts
people at high risk for colorectal cancer and endometrial (uterine) cancer.
While the risk level for ovarian cancer is much smaller with HNPCC than with
the BRCA1 and BRCA2 mutation, this genetic mutation does cause 1% of all
ovarian
cancers.
Some research shows that prolonged use of the fertility drug clomiphene
citrate, especially without achieving pregnancy, may increase risk for
developing ovarian cancer. Also, women who have had no children or who had
their first child after age 30 or experienced
menopause after age 50 may have an
increased risk of ovarian cancer, as there appears to be some correlation between
the number of menstrual cycles in a lifetime and the risk of ovarian cancer.
Recent information suggests that using estrogen
replacement therapy (ERT) increases the risk of developing ovarian cancer, and
that the risk increases with continued use. The risk among women who used ERT
longer than 10 years was almost double
that of women who had never used it, and the risk tripled
among those who used it for 20 years or more.
Interventions to decrease the burden
of ovarian cancer
There is no proven way to
prevent the development of ovarian cancer, but steps can be taken to reduce
risk. Women with a family history of ovarian cancer
and/or breast cancer may consider genetic testing, surgical removal of ovaries
and
fallopian tubes, and other steps that may help decrease risk. Decisions about
risk reduction should be made in consultation with family members and health
care professionals who can help assess risk and available options.
Conventional medical wisdom used to be that
there were no symptoms of ovarian cancer, but
recent research has documented a clear cluster of symptoms. It is important to
teach women
to be aware that a cluster of symptoms—
including back pain, fatigue, bloating, constipation, abdominal pain, and
urinary urgency—
may be warning signs when they occur frequently and increase in severity over
time.
There is no reliable screening
method for ovarian cancer at present.
Available methods now include a CA-125 blood test and a transvaginal ultrasound
for women who have symptoms suggesting ovarian cancer or who are at high risk
for the disease. Only about half of women with early-stage ovarian cancer have
elevated levels of CA-125, and the test sometimes produces false-positive
results. Neither of these tests is intended for general screening and neither
is accurate enough to justify use in routine care for women, but a clinical
trial is presently under way to determine the effectiveness of this combination
of tests for women at high risk.
At present numerous approaches are being tested to develop a
screening test, including studies based on proteomics (the study of cell
proteins). It is thought that changes in an
organ caused by the presence of a disease such as cancer may produce detectable
changes in the patterns of blood proteins, enabling testers to detect the
difference
between cancer and noncancer. Several specific patterns for ovarian cancer have
been identified, involving different analysis techniques, but tests need to be
validated in clinical trials involving large groups of women before it can be
determined if a reliable
screening test is possible using this approach.
Treatment for ovarian cancer is
generally predicated on the stage of the disease but almost always involves
surgery and chemotherapy. The kind of surgery
depends on how far the cancer has spread. Evidence shows that these complex
surgeries should be performed by a gynecologic oncologist, a cancer specialist
expert in this surgery. These specialists will stage the cancer appropriately
and will remove as much of the cancer as possible. Chemotherapy is almost
always given to women with ovarian cancer, especially those whose cancer has
spread beyond the ovary. In some instances,
radiation therapy or other treatments may
also be recommended.
Support
Access to support during and after treatment is important to
women with ovarian cancer, as many cancers recur and women may need support,
information, and assistance for years beyond initial diagnosis. Some DC area
cancer centers—notably
Georgetown
University
Lombardi
Cancer
Center
and George Washington University Cancer Institute, both in Ward 2—have ongoing
moderated support groups specifically for women with gynecologic cancers.
Initial ovarian cancer treatment, including surgery and
chemotherapy, often lasts for almost a year, and many women achieving remission
will require months beyond the end of treatment to achieve their former energy
levels and the abatement of chemotherapy’s side effects. Moreover, recurrence
rates are high, and women facing recurrence also face difficult chemotherapy
regimens and perhaps additional surgery. Women who are well supported by
family, friends, and compassionate employers face a less challenging time than
those who are not.
Most ovarian cancer chemotherapy can be given at physicians’
offices, at cancer centers and other hospitals, and, in rare instances, at
clinics. Many of the hospitals treating gynecologic cancers are located in
Wards 1, 2, 3, and 4 (Howard, George Washington,
Georgetown
, Sibley, and Walter Reed); Wards
6, 7, and 8 are distant from the area’s cancer centers. Women who rely on
public transportation to reach treatment face an
additional burden.
Barriers to care for ovarian cancer
There are several barriers to adequate care of ovarian cancer
patients, apart from the fact that there is no reliable screening tool for
ovarian cancer. Barriers include:
Lack of awareness of the subtle warning signs of
ovarian cancer by physicians and patients can produce a late diagnosis.
Moreover, some women erroneously believe that the Pap test also screens for
ovarian cancer.
Some medical
professionals may be unaware that ovarian cancer has symptoms and may
misdiagnose women in their care, especially since many of the symptoms of the
disease can be confused with other conditions.
Not infrequently women diagnosed with ovarian cancer complain
of long waits and of needing to see multiple
physicians to get a correct diagnosis.
Surgery is
sometimes performed on women with ovarian cancer by doctors with no specialized
training in gynecologic oncology. This results in less-than-optimal surgery and
inadequate screening, which may yield inadequate treatment throughout the
course of the disease.
For women who are
uninsured or underinsured, the District’s clinics and Medicaid may offer the
only avenue for getting treatment for ovarian cancer. There is no research
documenting these problems
in the District, but anecdotal evidence
suggests that in this environment women may
experience delayed treatments, missed
treatments, insufficient monitoring for disease progression and recurrence, no
appropriate treatment for side effects, and insufficient social support.
Patients who rely on the District’s Healthcare Alliance system suffer because
very few physicians and other health care professionals are willing to treat
them because of the
Alliance
’s
reputation for late and below-cost reimbursement for services and for
medications for managing the disease and side effects.

behaviors and to address barriers to
regular screening. Use a multilingual survey and a large enough sample to
analyze subgroups.
• Target outreach to Latinas and Asian women,
based on survey data.

proportion of cases classified as “stage
unknown” to less than 5% by 2010.
• Develop physician
awareness programs to make community-based primary care physicians,
gynecologists, and surgeons aware of the need for appropriate use of
gynecologic oncologists.
GOAL 4: Improve the quality of
care for underinsured and uninsured women in the
District who have gynecologic cancer.
1)
Increase information and support to DC clinics and providers treating the
target
population by 2010.
• Implement a patient navigation system in clinics
for women with gynecologic cancers.

Facts in brief:
• Colorectal cancer, the third most common cancer in the country, is responsible
for 10% of all cancer deaths. There
were an estimated 146,940 new cases
nationally in 2004 and 56,730 deaths.
Among men and women, DC has the
highest mortality rate from colorectal
cancer, higher than the national norm.
• The lifetime risk of
developing colorectal cancer for both men and women is 6%.
Americans who die from colorectal
cancer lose on average 13.4 years of life.
• Since 1985, the
incidence of and mortality rate for colorectal cancer has
been declining about 2% a year,
although the decline has been more prominent
among Whites. The decline is
attributed largely to increased screening and
surveillance and improvements in
treatment.
• Early detection
reduces mortality. Most invasive colorectal cancers begin as polyps, and it
takes an average 5 to 15 years before polyps become malignant and form invasive
cancers.
• The cancer is detected
at an early stage, when survival rates are better, among only 27% of White men,
25% of White women, 24% of Black men, and 23% of Black women. For all stages
combined, the relative 5-year survival rate is 63% for Whites and 53% for
Blacks.
• Everyone age 50 or
over is at risk and should be screened.
• If there is to be only
one colonoscopy screening in a lifetime, the most effective age to screen is at
60. Data suggest that screening at this age can reduce mortality from
colorectal cancer by 70%. It is better to screen once than not at all.
The burden of colorectal cancer in
Washington
,
DC
Among
U.S.
men and women,
Washington
DC
has the highest mortality rate from colorectal cancer, higher (at 25.0 deaths
per 100,000 people) than the average
U.S.
rate (21.2 cases/100,000) (see
Table 1). Against a
25-year trend downward in colorectal mortality
rates among Blacks in the
U.S.
,
the past 5 years have seen an increase in colorectal mortality rates in
Blacks in DC..
The annual
incidence rate for DC (59.8 cases/
100,000) is higher than the national incidence
(53.1
cases/100,000). And the rates of colorectal cancer are higher for Blacks than
for Whites in all age groups. In DC, the incidence of colorectal cancer is
highest in Wards 2 and 5 and lowest in Ward 3 (see Table 2). Ward 8, despite
its high level of poverty, has a relatively low number of cases, perhaps
because young people comprise a significant proportion of the ward. For
2005, the estimated number of new cases of colorectal cancer in Washington DC
(340) is greater than the estimated number of lung cancer cases (310)—and the
number of expected deaths from colorectal cancer in DC is 130.
Risk factors
Nonmodifiable Risk Factors
Age is the most common risk
factor for colorectal cancer. The incidence of the disease increases with age,
especially after 60. Thus, screening becomes more effective with age.
Most
colorectal cancer is found in people who are not at high risk. But specific
mutations have been found in two types of colorectal cancer sometimes inherited
in families (see Genetic testing).
Modifiable risk factors
Nearly all
colorectal
cancer evolves from adenomas, benign tumors that often grow as a polyp. Polyps
are common; when large, they may progress to invasive cancer. But polyps can be
both identified and removed through colonoscopy screening. Colonoscopy is
required to remove the polyps before they become cancerous. Post-mortem studies
show that 25% to 50% of the populationwill have single or multiple adenomas in
the colon by age 70.
Inflammatory
bowel disease is associated with a risk for colorectal cancer. Ulcerative
colitis that persists for many years may lead to an usually high risk. Crohn’s
disease (sometimes called regional ileitis) is also, but infrequently,
associated with the cancer.
Studies suggest that
obesity is a risk factor for colorectal cancer. Other factors have been
implicated, including low consumption of fiber and high consumption of red meat
and fat, but these findings have not been substantiated.
Reducing deaths from colorectal cancer
The main interventions to reduce deaths from colorectal
cancer include prevention, genetic testing (when
appropriate), screening and early detection of precancerous
lesions and cancer.
Primary prevention
Dietary interventions are designed to promote and increase the consumption of
foods and nutrients known to reduce the risk of cancer. This means less meat
and more fruits, vegetables, and fiber. It also means reducing obesity, a
recognized risk factor for colorectal cancer and many other diseases.
There is
evidence that regular physical activity may help prevent the onset of many
forms of cancer.
Genetic testing
Individuals
with a family history of colorectal cancer can have their DNA tested to
determine whether they have inherited the HNPCC syndrome (hereditary
nonpolyposis colorectal cancer) or the FAP (familial adenomatosis polyposis)
syndrome, two mutations known to predispose families to colorectal cancer. The
HNPCC syndrome often occurs in patients younger than 50, so early testing is
advised whenever there is a family history of colorectal cancer.
Screening and early detection
Screening improves the chances
of early
detection and the removal of benign
adenomatous polyps (precancerous lesions) and the detection of small, localized
cancers that are surgically curable. Unfortunately in DC, two-thirds of
colorectal cancers are diagnosed beyond these pre-cancerous or early
(localized) stage (see Table 3). The National Cancer
Institute estimates that wide use of screening could save more than 20,000
lives a year.
Four screening tests are in common use:
the
fecal occult blood test, sigmoidoscopy, colonoscopy, and radiological
visualization with double-contrast barium enema. Only the fecal
occult blood test can be considered a true screening test because of its
reliability, low cost, simplicity, and availability.
The most common screening test for colorectal cancer, FOBT detects small
quantities of blood
present in the stool. The test, which can be performed at home, is simple,
inexpensive, and available from drug stores. To reduce the risk of cancer, the
test should be performed annually for at least 10 years, under a
physician’s guidance.
Because FOBT is a screening test and not a diagnostic test, a positive result
should be followed by a colonoscopy. Unfortunately, a high rate of
false-positive results greatly increases the number of unnecessary
colonoscopies performed. Physicians should inform patients in advance about
substances in the diet (such as vitamin C) that can produce
misleading test results.
A standard procedure that
examines only the distal or left colon and rectum, the sigmoidoscopy is only
moderately expensive and takes only a short time. Although sigmoidoscopy is
considered effective in reducing deaths from colorectal
cancer, many physicians do not recommend it because it examines only the left
side of the colon. If cancer or precancerous lesions are found, colonoscopy
must follow.
Fiberoptic colonoscopy is
the gold standard in screening, permitting visualization of the inside of the
entire colon. Colonoscopy has
substantial drawbacks as a screening test. It requires highly
trained personnel and is expensive and time-consuming. An intravenous catheter
is used to administer sedatives, recovery time is one hour, and a second person
must accompany the patient home. But colonoscopy is the only procedure that can
identify and remove precancerous polyps and detect early cancer. Colonoscopy
should be required of everyone in whom cancer is suspected, who has had
previous colorectal cancer, or who is at very high risk. Colonoscopy is most
effective in preventing cancer if performed between the ages of 56 and 66, when
precancerous polyps are most likely to be present.
Often used for
surveillance by radiologists, this may be useful in some cases for identifying
polyps that are difficult to recognize by colonoscopy. Most often, patients are
referred by their physician for this procedure.
Follow-up for high-risk patients
Repeated screening at specified intervals is recommended for
individuals who are at high risk because of previous polyps, a family
history of the disease, inflammatory bowel disease, or curative-intent
resection (surgery) for colorectal cancer. The idea is to detect cancers early
so they can be treated before they are able to metastasize. Patients with a
history of polyps or surgery for colorectal cancer should undergo regular
surveillance, because new polyps or additional primary
cancers often arise in the colon years later.
Barriers to reducing the cancer burden
Screening rates for colorectal cancer remain lower than those
for other cancers. Less than
half of the
U.S.
population age 50 and older
takes advantage of colorectal cancer tests within the recommended time
intervals,
according to a National Health Interview Survey. A successful prevention and
control program requires recognizing the barriers to screening for cancer and
finding the resources to overcome them—whether they are associated with patients,
health care providers,
or the health care system itself. In the final analysis, the most commonly
reported
barriers to screening are a lack of awareness about testing and the physician’s
failure to recommend testing.
Common barriers as patients see them
The public appears not to have been well informed about the
risk of, or the risk factors associated with, colorectal cancer. Despite
widespread publicity about colon cancer, increased reimbursement for screening,
and data from national health surveys, the screening rates for colorectal
cancer are significantly lower than those recorded for breast or cervical
cancer. Common reasons
for not undergoing screening include
• Practical issues, such as inconvenience
(an entire day is required for a colonoscopy)
• Conflicts with work or family
• Lack of insurance or medical coverage
• Lack of interest
• The tests’ unpleasantness
• Anxiety about the results
• Lack of access
• Lack of awareness about testing
• Fear of cancer
• The idea that cancer cannot be cured
• Age (young patients are less compliant
than older patients)
• The physician’s
failure to recommend
the test.
Barriers among health care providers
The key factor in promoting cancer screening is a
physician-patient relationship of trust.
Patients are most likely to comply with
screening if their physician recommends it. One important barrier to screening
is the health care providers’ failure to take a careful
family history of cancer and to refer family members for testing if there is evidence
of a familial pattern. Other barriers include little or
no access to screening facilities, lack of trained personnel,
lack of information about screening
centers, and practice- or capacity-related problems.
Barriers in the health care system
Economics and limited access are barriers
to screening. Reimbursement seems to have
a positive effect on screening rates. The relative odds of Medicare
beneficiaries with incomes below $25,000 a year getting a
sigmoidoscopy increased between 1997
and 1999. All groups should be made aware that Medicare provides reimbursement
for colonoscopic screening performed every 10 years for patients at average
risk.
Rules about reimbursement coverage need to be clarified
because lack of knowledge or widespread variation in reimbursement rules and
application serve only to discourage screening. Screening should be included in
health plans offered by both private and government sources, and reimbursement
should not be so low as to discourage screening. Insurers should be made aware
that routine screening is cost-effective because it prevents costly treatment
and hospitalization.
GOAL 1: Reduce the mortality rate in DC from colorectal
cancer by 10%.
GOAL 2: Reduce the incidence of invasive disease in DC by
10%.
1) Increase to 50% the proportion of
colorectal cancer detected at the local stage
for both men and women by 2010.
2) Increase to 50% the proportion of the
adult population that reports having had a
fecal occult blood test in the previous
2 years by 2010.
3) Increase to 60% the percentage of
the population age 50 or older screened by
sigmoidoscopy or colonoscopy by 2010.
• Encourage professional
organizations to promote screening among their members.
Collaborate with DC’s medical societies to promote colorectal cancer prevention
and
control and to overcome barriers to screening. Seek representation on the
Public Health
and Communications Council of the Medical Society in
Washington
. Invite professional
medical organizations, especially for primary care, to become active members of
the DC
Cancer Coalition.
• Develop the
infrastructure to provide screening for all DC residents, whatever their
cultural
or ethnic background. Do this through collaboration among primary care
physicians, internists, surgeons, and gastroenterologists. Create an enduring
collaboration that includes public
enterprises, research communities, and professional organizations with an
interest in the causes, prevention, and consequences of colorectal cancer.
• Develop community
education and outreach campaigns about common risk factors and
early symptoms, the benefits of screening and lifestyle modification, centers for
screening for all cancers, treatment facilities and support services, and the
availability of financial assistance.
• Reduce cultural,
ethnic, and financial barriers to screening by targeting education programs
to the medically underserved and high-risk populations—taking into account
language barriers and low rates of literacy.
• Encourage athletes,
television personalities, politicians, teachers, and other role models to serve
as advocates for routine screening (whatever the test).
• Increase the number of
physicians who recommend screening to patients and who routinely take a family
history of cancer. Train physicians to inquire about every patient’s family
history of cancer, whatever the purpose of their medical visit, and invite family
members to undergo screening or genetic testing if a familial risk pattern
exists.
• Encourage physicians
to use reminder or other systems for recalling patients for screening.
• Make health care
professionals aware of centers in DC for colorectal cancer screening and
surveillance, of genetic testing and genetic counseling services, of treatment
facilities, and
of cancer rehabilitation centers.
• Through professional
associations, arrange for scientific presentations, newsletter items,
and postgraduate education about colorectal cancer prevention and control,
including the benefits of early detection.
• Encourage at least
once-in-a-lifetime colonoscopy screening at about 60 as a “rite of
passage.” At least one colonoscopy is better than none, and colonoscopy is most
effective
at the age of 60.
• Promote better
insurance coverage and other forms of assistance for colorectal screening.

Facts in brief:
• Prostate
cancer is the second leading cause of cancer deaths among men
in the
U.S.
—second only to lung cancer.
One in three new cancer cases in men
arises in the prostate gland.
• The projected number
of new cases nationally in 2005 is 230,090—with an
estimated 30,350 men dying from the
disease. This is the most commonly
diagnosed non-skin male cancer in most
Western countries.
• Estimates are that 610
men in the District will be diagnosed with prostate cancer
and 80 men will die from the disease
in 2005.
• The lifetime risk of
being diagnosed with invasive prostate cancer is 1 in 6. The
risk increases from the age of 50 on.
Men at higher risk (because they have fathers or
blood-related uncles who had prostate cancer at an early age) should
begin testing at age 45.
• DC has the highest
mortality rate from prostate cancer in the nation. The rate is twice as high in
Black men as in White. Incidence rates for Black men in DC are among the
highest in the nation. The incidence and death rates for Black men are highest
the world over, according to the International Agency for Cancer Research. The
risk is lowest in men of Asian descent.
• Nationally, the median
age for diagnosis is 66 for Black men and 69 for White men. The median age of
death from prostate cancer is 77 for Black men and 79 for White.
• On average, 9 years of
life are lost to prostate cancer.
• The causes of prostate
cancer are largely unknown.
• Prostate cancer
eventually affects nearly all men but is clinically unimportant in most men.
An uneven burden
Prostate cancer does not affect everyone equally. Its impact
on Black men is
especially hard. As far back as the 1930s, investigators documented racial
differences in survival and mortality. The explanations offered today are the
same as those offered years ago—including inadequate medical care,
environmental factors, cultural differences, diet, hereditary factors, and
social habits.
From 1998 through 2002, there were 2,671 new cases of
prostate cancer in the
District of
Columbia
(see Table 1).
Incidence and mortality rates (Tables 1 and 2) are highest in
Wards 2 and 4. The incidence of prostate cancer in White men began to decline
nationally in 1993 and for Black men in 1994. Differences in incidence,
clinical stage, and histological (cell) grade are still found in every age
group among White and Black men.
Prevention
Currently, there is no known way to prevent prostate cancer,
although the National Cancer Institute is conducting research on prevention.
Men are usually advised to avoid or minimize risk factors, but this is not
always possible.
Risk factors for prostate cancer
Common risk factors include age, race,
family history of the disease, diet, and serum androgen levels. Nearly all risk
factors have been found through studies of White men, so additional risk
factors specific to Black men are unknown. Most investigators have assumed that
risk factors operate similarly across racial groups.
Age is the strongest risk factor.
Prostate cancer is largely a disease of older men; it is rare below the age of
50. The risk increases steadily with age and more than half of all men will
have some cancerous growth by the time they are 80, although in most cases it
goes unnoticed. Half of all cases are registered in men over 75 and 90% of
prostate cancer deaths occur in men 65 and over.
Prostate cancer’s devastating effects
on Black men are reflected in national data. For the years 1998–2002 in DC, the
incidence rate of prostate cancer in White men was 160.8 for all ages and 252.1
for Black
men. The mortality rate per 100,000 men was 23.4 for White
men and 66.4 for Black.
The onset of invasive prostate cancer comes at a younger age
in Black men, and Black men also register premalignant changes earlier. HGPIN
(high-grade prostatic intraepithelial neoplasia), a premalignant lesion that
progresses to invasive cancer, is more prevalent in Black men than in White.
HGPIN was found at autopsy in 18% of Black men in their forties (compared with
14% of White men the same age); in 31% of Black men in their
fifties (21% of White men); in 69% of Black men in their sixties (38% of White
men); in 78% of Black men in their seventies (50% of White men); and in 86% of
Black men in their eighties (68% of White men). More extensive HGPIN developed
earlier in Black men
younger than 60 than in White men the same age. The higher prevalence of HGPIN
in Black men may explain the higher incidence of prostate cancer in this
population, but
questions remain as to what causes the higher incidence of HGPIN at a
relatively young age
in Black men.
Within a clinical setting, Black men are more likely to
present with advanced-stage disease and less differentiated tumors than White
men. The reason is unknown.
Differences between Black and White men
are evident in many studies. In a military population in which all men have
equal access to care, for example, Black men had tumors
averaging two and a half times greater in
volume at diagnosis, had higher mean
(geometric) pretreatment PSA levels, and
were 3 years younger on average than White men. The military setting may
eliminate
limitations on access but not necessarily
socioeconomic factors or environmental
differences that affect prostate
